Productive employees are an asset to all companies. For instance, productive employees can produce more output in less time, reducing operational costs. Workplace safety promotes the wellness of employees and employers alike. Better safety equates to better health. Healthier employees do tasks more efficiently, and they are happier in general. There are very few accidents in a safe working environment. This results in less downtime for safety investigations and reduces costs for worker s compensation. This also reduces the time needed for employees to heal from injuries. Damage to industrial equipment creates costs for replacement and repair. Avoiding workplace injuries and damage to industrial equipment will incur fewer expenses and increase profit. If employers are concerned about the safety of their employees, the employees are more confident and comfortable in general. Also, absenteeism rates drop, and employees are more focused on doing their tasks. 1. Increased productivity and efficiency As mentioned earlier, your employees need to focus entirely on their work, and to do so, they need to be relieved of the worries and stress that come with unsafe and unhealthy working conditions. If the employees at your workplace are constantly under the stress regarding the future of themselves as well as their dependents, they will not be able to live up to the amount of productivity and efficiency that is required of them, and which is necessary for the company. 2. Reduced compensation cost As the common saying goes, Prevention is better than cure . Indeed, instead of having to pay a huge sum to compensate for poor employee health, it is much easier to invest in a healthy and safe workplace. Every time an unfortunate accident or health hazard occurs, you will have to bear the expenses of both the compensation claims of your employees and well the hiring costs for temporary staff. Not to mention, these incidents would also come up with a huge ordeal of paperwork. |
If all, or at least most, companies engage in a safe and healthy work environment, it will create a more sustainable, and safer work environment overall.

Burn Injuries There are four categories, or degrees, of burn injuries, signifying the depth to which tissue is damaged: First degree burns. This injury is comparable to sunburn. The victim can expect minor pain and redness erythema on the epidermis, the top layer of skin. Generally, the burn will heal over a few days. Some evidence suggests that these burns may be associated with an increased risk of skin cancer later in life. Second degree burns. The damage extends to the lower layers of the skin the papillary or reticular dermis. Blisters form, and the site is moist and extremely painful to the touch. Bacterial infection and cellulitis are risks with this category of burns. Healing may require several weeks to a month. Third degree burns. The skin is charred at all layers and appears dry and leathery. The site is usually painless because of nerve damage. |
Third degree burns. The skin is charred at all layers and appears dry and leathery. The site is usually painless because of nerve damage. Natural healing is impossible; the skin must be surgically excised and skin grafts used. The chance of infection is very high. Fourth degree burns. The skin is incinerated at all layers; muscle tissue and bone are charred. Severe nerve damage renders the injury site painless. Thisis a life-threatening injury that may require amputation or extensive plastic surgery. The risk of infection and gangrene is very high. B. Respiratory Injuries The combination of suffocation also called asphyxiation and smoke inhalation during a Wilmington residential fire can be devastating. Breathing injuries are the primary causes of death in U.S. house fires. There are three different components of these injuries: Oxygen-depleted air. A burning fire consumes oxygen from the air. The remaining mix of nitrogen, carbon monoxide, and carbon dioxide cannot keep a person alive. Carbon monoxide is toxic and bonds more closely than oxygen to the hemoglobin in the blood, making it difficult to revive a patient with oxygen therapy alone. Prolonged exposure to oxygen-depleted air causes confusion, drowsiness, and death. Inhaled hot gases. Inhaling super-heated combustion products can scorch and scar nasal passages and lung tissue. This can lead to permanent and disabling lung problems. Smoke. Smoke consists of carbon particles, ash, volatile organic compounds, and a variety of toxic gases including hydrogen sulfide. These can damage the respiratory system permanently, congest or obstruct breathing, and cause seizures and coma. Fire Hazards and Control Measures Fire hazards refer to any situation, substance, or event that has the potential to cause a fire or increase the likelihood of a fire occurring.

These systems can be automatic or manual, depending on the specific application. 6. Emergency Planning And Preparedness This involves creating fire escape plans, conducting fire drills and training, and establishing emergency communication systems. Fire escape plans are essential for ensuring occupants know the quickest and safest routes to exit a building in case of a fire. Regular fire drills and training sessions help familiarize occupants with evacuation procedures and the proper use of fire safety equipment. Emergency communication systems, such as public address systems and emergency call boxes, allow for rapid dissemination of information during a crisis, enabling people to respond efficiently and effectively. 7. Systems Of Work Systems of work must be designed to minimize fire risk. The degree to which this is done and the exact procedures implemented should be decided through the risk assessment process. An example of a safe system of work applied to fire safety is using a permit-to-work system to control hot work where naked flames or a significant ignition source will be created . Typical Precautions For Control Of Hot Work: Combustible and flammable materials are removed from the work area. Items that cannot be removed are covered with fire-retardant blankets. The floor is swept clean. Any wooden floor is damped down. |
Items that cannot be removed are covered with fire-retardant blankets. The floor is swept clean. Any wooden floor is damped down. A suitable fire extinguisher is at hand. A fire-watcher is present in the area while the work is carried out. The work area is visited routinely after the work has finished checking the area for smoldering. 8. Good Housekeeping Good housekeeping is fundamental to fire safety and is about keeping the workplace: Waste-free by removing waste regularly e.g. emptying full litter bins so that it does not build up and increase the fire risk as a potential fuel source. Tidy so that combustible and flammable materials are returned to safe storage after use e.g. solvents returned to the solvent store . Well-ordered so that fuel and ignition sources separate e.g. ensuring fan heaters are not obstructed . Pedestrian routes should also be kept clear e.g. with no obstructions by the fire-escape door , so they can be used during a fire evacuation. Fire escape plansIf on fire Stop, Drop, Cover and Roll Smother the flames with a blanket Move away from heat source First aid for burn injuries Protect your own safety at all times For all burns apply cold running tap water for at least 20 minutes If running water not available, wet 2 cloths and alternate them onto the burn every 2 minutes Keep the rest of the body warm Do NOT use ice, butter, creams, etc. Remove clothing and jewellery as they can hold heat on the burn and jewellery can stop blood flow to the burn. Seek medical attention for any burn bigger than a 20 cent coin, or that blisters or if there are any concerns. Ensure that all adults in the household know and understand proper first aid. Where appropriate, children should be taught general first aid principles. STOoPStrip hot clothes jewellery. Turn on cool tap never use ice .Run burn under cool water for10 minutes. Keep the rest of theperson warm. Organise medical assistance 999, A E, GP .Protect burn with cling film orclean cloth Do not use dressings,fluffy cloth, creams or lotions . |
In these situations, it is crucial to shut off the power supply first before extinguishing the fire using an appropriate fire extinguisher. Class D Fires Class D fires involve combustible metals, such as magnesium or titanium. These fires require special extinguishing agents designed for Class D fires, as regular extinguishing methods may be ineffective or even dangerous. Evacuation Procedures In the event of a fire, quick and safe evacuation is vital. Here are the key steps to follow during an evacuation: Alerting Others Immediately notify others about the fire by activating fire alarms or verbally informing them. Time is of the essence, and early warning can save lives. Assessing the Situation Before moving towards an exit, assess the situation for any potential hazards or obstacles. If necessary, choose an alternative evacuation route. Escaping Safely Move swiftly but calmly towards the nearest exit, following the predetermined escape plan. Crawl low if there is smoke, as cleaner air is closer to the floor. Do not use elevators during a fire. Fire Safety in Specific Settings Fire safety practices may vary depending on the specific setting. Here are some considerations for different environments:Home Fire Safety Install smoke detectors on each floor of your home. Keep flammable materials away from heat sources. Develop and practice a family fire escape plan. Teach children about fire safety and the hazards of playing with fire. Workplace Fire Safety Familiarize yourself with workplace fire safety protocols and evacuation plans. Attend fire safety training sessions provided by your employer. Keep work areas clean and free from clutter. Report any potential fire hazards to the appropriate authority. School Fire Safety Schools should have well-maintained fire alarm systems and conduct regular fire drills. Educate students about fire safety and the importance of following fire evacuation procedures. Ensure that fire exits are clearly marked and accessible. Have a designated assembly area for students and staff during evacuations. Fire Safety Equipment and Maintenance Regular maintenance of fire safety equipment ensures its effectiveness when needed. Consider the following: Fire Sprinkler Systems Fire sprinkler systems automatically detect and suppress fires. Regular inspections and maintenance are essential to ensure their proper functioning. Fire Alarm Systems Fire alarm systems provide early warning of a fire. Test these systems regularly and replace batteries as needed. If a fire alarm is faulty, report it immediately for prompt repair. Fire Extinguisher Maintenance Fire extinguishers should be inspected and serviced annually by professionals.

Additionally, knowledge of basic first aid techniques for fire-related injuries equips us to provide immediate assistance and support to those in need. Remember, fire safety is a collective responsibility. By taking proactive measures, spreading awareness, and practicing fire safety in our homes, workplaces, and schools, we can create a safer environment for everyone. Firefighting methods Cooling method The principle of this fire extinguishing method is to spray the fire extinguishing agent directly on the burning object to reduce the temperature of combustion below the ignition point and stop the combustion. Or spray the fire extinguishing agent on the material near the fire source, so that it will not form a new fire point due to the heat radiation of the flame. The cooling fire extinguishing method is one of the main methods of fire extinguishing, and water and carbon dioxide are commonly used as fire extinguishing agents to cool down and extinguish the fire. The fire extinguishing agent does not participate in the chemical reaction in the combustion process during the fire extinguishing process. This method is a physical fire extinguishing method. Isolation method The isolation fire extinguishing method is to isolate or remove the burning material from the surrounding unburned combustible material, interrupt the supply of combustible material, and stop the combustion due to lack of combustible material. The specific methods are:1. Remove combustible, combustible, explosive and combustion-supporting materials near the fire source; 2. Close the valves of combustible gas and liquid pipelines to reduce and prevent combustible substances from entering the combustion zone; 3. Try to block the scattered flammable and combustible liquids; 4. Demolition of flammable buildings adjacent to the fire source to form a space zone to prevent the spread of fire. Asphyxiation The suffocation fire extinguishing method is a fire extinguishing method that prevents the air from flowing into the combustion zone or uses the incombustible zone or dilutes the air with incombustible substances, so that the burning substance does not get enough oxygen and extinguishes. |

The specific method is: 1. Cover the burning material with incombustible or non-combustible substances such as sand, cement, wet sack, wet quilt; 2. Spraying water spray, dry powder, foam and other fire extinguishing agents to cover the burning material; 3. Fill containers and equipment in fire with water vapor, nitrogen, carbon dioxide and other inert gases; 4. Airtight fire buildings, equipment and holes; 5. Spray non-combustible gas or non-combustible liquid such as carbon dioxide, nitrogen, carbon tetrachloride, etc. Into the combustion area or on the combustion materialElectrical accidents Electrical hazards A hazard is something that has the potential to cause harm. Electricity is a hazard, as it can cause severe injury and even death. The main hazards are: Contact with live electrical parts resulting in electric shock and burns. Electrical faults, causing fires. Fire or explosions from electricity igniting a flammable or explosive atmosphere. Uncontrolled electrical hazards can cause Electrical injuries. Severe pain Heart failure Breathing difficulties Muscle spasms, which can cause other injuries such as fractures Tissue, nerve and muscle damage Burns Electrocution Arc flash Electric shock Other serious injuries Fires or explosions, posing a threat to life, property, and the overall safety of a place and its occupantsElectric shock A person can receive an electric shock if they come into contact with live electrical parts or if electricity arcs. An electric shock can result in minor or severe harm. It can also cause death, which is known as electrocution. Coming into contact with live electrical parts can: Cause severe pain. Stop the heart from beating properly. Prevent a person from breathing. |
Coming into contact with live electrical parts can: Cause severe pain. Stop the heart from beating properly. Prevent a person from breathing. Cause muscle spasms, which can cause other injuries such as fractures. Cause tissue, nerve and muscle damage. The injuries from an electric shock are varied and will depend on: The voltage and current The higher the voltage and current, the likelihood of death increases. However, just 50 volts AC can cause a person s heart to stop and prevent breathing. The path of the current If it travels through vital organs, it can cause more damage. The length of exposure to the current Injuries will be more severe if exposed for longer. The resistance Wet skin reduces resistance and allows for the current to flow more freely. It is the electrical current that makes electricity dangerous, as it can flow through the body. Alternating current AC is considered more dangerous than direct current DC , as it can cause internal damage even at a smaller magnitude. However, both AC and DC are dangerous, above a particular voltage, and have different effects on the body. The voltage allows the current to enter the body, as it reduces the resistance. It is not always the electric shock that causes injury either. It can contribute to other accidents, e.g. falling from a ladder whilst working at height. Burns When an electrical current flows through the body, it heats tissues as it travels, which can cause severe burns and internal tissue damage. Electrical burns can be severely disabling and can leave extensive scarring. Severe burns may even result in major surgery and amputations. Burns are more common with high voltages, but they can occur at 230 volts if the current flows for longer. Burns can also occur when a person: Receives an electric shock due to arcing jumping . Arcing also creates ultraviolet radiation, which can damage a person s eyes. Touches electrical equipment that has become hot due to a fault thermal burns . Is caught in a fire caused by an electrical fault. Fire and explosion Workers do not have to come into direct contact with electricity to be harmed by it. Electricity can be an ignition source, which can cause fires and even explosions if there is an explosive atmosphere. Electrical accidents involving fires and explosions can result in multiple fatalities, severe injuries and extensive property damage. |
Fire and explosion Workers do not have to come into direct contact with electricity to be harmed by it. Electricity can be an ignition source, which can cause fires and even explosions if there is an explosive atmosphere. Electrical accidents involving fires and explosions can result in multiple fatalities, severe injuries and extensive property damage. Injuries can vary depending on the seriousness of the fire explosion and how far a person is from the event. Most electrical accidents and injuries occur as a result of the following: Not isolating electrical installations and equipment properly before working on them. Working on or near live electrical systems thought to be dead. Inadequate information and instruction provided on electrical risks. A lack of training and competence to undertake tasks involving electricity. Inadequate training is one of the main causes of electrical accidents. An unsafe safe system of work. Using electrical equipment in wet conditions or touching it with wet hands. Faulty, damaged and defective electrical systems, wiring and equipment. Misuse of electrical equipment and appliances. Poor design, construction and installation of electrical installations and wiring. Overloading of electrical systems causing them to overheat, e.g. plugging too many devices into a circuit and using incorrectly rated fuses. Inadequate maintenance, inspection and testing of electrical systems and equipment. The risk of an electrical accident will be higher for those working directly on or adjacent to live electrical equipment and with higher voltages. However, all workers and others on the premises are at some risk where electricity is used in the workplace In addition to the hierarchy of control, other measures can also minimize electrical risks. Here are some tips: Do Ensure the power supply is regularly tested by a competent person and taken out of service if unsafe. Keep isolators and other electrical systems clear at all times and clearly identify them with signs. Ensure anyone working with electricity is trained and competent. The level required will depend on the task, e.g. maintenance of electrical equipment will require a higher level of training and competence. Use portable electrical equipment safely, e.g. not misusing it, using it for its intended purpose and storing it properly after use. Fully pull out electrical extension reels when in use to prevent overheating. When defrosting raw foods, keep them away from other foods to prevent cross-contamination. Complete a pre-use check of electrical equipment to ensure it is safe. |
Fully pull out electrical extension reels when in use to prevent overheating. When defrosting raw foods, keep them away from other foods to prevent cross-contamination. Complete a pre-use check of electrical equipment to ensure it is safe. Switch off and unplug electrical equipment during maintenance, cleaning, repairing or adjusting. Switch off all non-essential electrical equipment at the end of the working day. Not only is this safer, but it also saves energy. Do not Do not overload sockets, as this can cause overheating and fire. Do not force a plug into a socket if it does not fit. Do not route electrical cables where they could be damaged or where someone could trip. Use cable protectors if they cannot be re-routed. Do not use electrical equipment with wet hands or near water. Do not keep liquids by electrical equipment, e.g. open drinks next to computers. Do not plug multiple extension leads together daisy-chaining . Do not pull electrical equipment out of a socket by its lead. Always grip the plug. Electrical shock: First aid The danger from an electrical shock depends on the type of current, how high the voltage is, how the current traveled through the body, the person's overall health and how quickly the person is treated. An electrical shock may cause burns, or it may leave no visible mark on the skin. In either case, an electrical current passing through the body can cause damage inside the body, cardiac arrest or other injury. Under certain circumstances, even a small amount of electricity can be fatal. When to contact your doctor A person who has been injured by contact with electricity should be seen by a health care provider. Symptoms of an electrical injury Often, the main symptom of the electrical injury is a skin burn. High-voltage injuries may cause severe internal burns. If muscle damage is extensive, it swells to the extent that the arteries are compressed. Toddlers who bite or suck on extension cords can burn their mouth and lips, causing added deformities and growth problems of the face and other facial structures. A minor shock may cause muscle pain causing the person to startle and or fall. The electricity may also cause abnormal heart rhythms causing heart problems or exacerbating current ones. The nerves and brain may also be affected which may cause memory and behavioral problems. |
A minor shock may cause muscle pain causing the person to startle and or fall. The electricity may also cause abnormal heart rhythms causing heart problems or exacerbating current ones. The nerves and brain may also be affected which may cause memory and behavioral problems. Caution Don't touch an injured person who is still in contact with an electrical current. Call your local emergency number if the source of the burn is a high-voltage wire or lightning. Don't get near high-voltage wires until the power is turned off. Overhead powerlines usually aren't insulated. Stay at least 20 feet about 6 meters away farther if wires are jumping and sparking. Don't move a person with an electrical injury unless there is immediate danger. When to seek emergency care Call your local emergency number if the injured person experiences: Severe burns Confusion Difficulty breathing Heart rhythm problems Cardiac arrest Muscle pain and contractions Seizures Loss of consciousness Take these actions immediately while waiting for medical help: 1. Turn off the source of electricity, if possible. If not, use a dry, nonconducting object made of cardboard, plastic or wood to move the source away from you and the injured person. 2. Begin CPR if the person shows no signs of circulation, such as breathing, coughing or movement. 3. Try to prevent the injured person from becoming chilled. 4. Apply a bandage. 5. Separate the person from the current source before giving any first aid. 6. Call the emergency number or nearby medical responders if available . 7. If the electricity source cannot be turned off, use insulating objects such as brooms or chair to push the person affected away from the currentElectrical Injuries: first aid Electrical injuries occur when an electrical current passes through the body that causes inadvertent damage and burns to the internal organs thereby affecting their functions. Faulty electrical lines, machinery and appliances may result in an electrical injury. Others causes of electrical injuries may occur with contact with household wiring or power lines. There are a number of factors that determine the intensity of the injury such as the type of current, the duration of exposure and many others.

Conclusion Assembling and disassembling a computer system is not a difficult task but requires keen observation and knowledge of the different components of thesystem. You need to be extra careful when fitting in these components and make sure that they are not fitted forcefully but firmly. In case of hardware failure or to install new add-on cards, you need to have good knowledge to assemble and disassemble a computer system Major parts of a computer case https: www.youtube.com watch?v HB4I2CgkcCo Inside a computer Have you ever looked inside a computer case, or seen pictures of the inside of one? The small parts may look complicated, but the inside of a computer case isn't really all that mysterious. This lesson will help you master some of the basic terminology and understand a bit more about what goes on inside a computer. Motherboard The motherboard is the computer's main circuit board. It's a thin plate that holds the CPU, memory, connectors for the hard drive and optical drives, expansion cards to control the video and audio, and connections to your computer's ports such as USB ports . The motherboard connects directly or indirectly to every part of the computer. CPU processor The central processing unit CPU , also called a processor, is located inside the computer case on the motherboard. It is sometimes called the brain of the computer, and its job is to carry out commands. Whenever you press a key, click the mouse, or start an application, you're sending instructions to the CPU. The CPU is usually a two-inch ceramic square with a silicon chip located inside. The chip is usually about the size of a thumbnail. The CPU fits into the motherboard's CPU socket, which is covered by the heat sink, an object that absorbs heat from the CPU. A processor's speed is measured in megahertz MHz , or millions of instructions per second; and gigahertz GHz , or billions of instructions per second. A faster processor can execute instructions more quickly. |
The CPU fits into the motherboard's CPU socket, which is covered by the heat sink, an object that absorbs heat from the CPU. A processor's speed is measured in megahertz MHz , or millions of instructions per second; and gigahertz GHz , or billions of instructions per second. A faster processor can execute instructions more quickly. However, the actual speed of the computer depends on the speed of many different components not just the processor. RAM random access memory RAM is your system's short-term memory. Whenever your computer performs calculations, it temporarily stores the data in the RAM until it is needed. This short-term memory disappears when the computer is turned off. If you're working on a document, spreadsheet, or other type of file, you'll need to save it to avoid losing it. When you save a file, the data is written to the hard drive, which acts as long-term storage. RAM is measured in megabytes MB or gigabytes GB . The more RAM you have, the more things your computer can do at the same time. If you don't have enough RAM, you may notice that your computer is sluggish whenyou have several programs open. Because of this, many people add extra RAM to their computers to improve performance. Hard drive The hard drive is where your software, documents, and other files are stored. The hard drive is long-term storage, which means the data is still saved even if you turn the computer off or unplug it. When you run a program or open a file, the computer copies some of the data from the hard drive onto the RAM. When you save a file, the data is copied back to the hard drive. The faster the hard drive, the faster your computer can start up and load programs. Power supply unit The power supply unit in a computer converts the power from the wall outlet to the type of power needed by the computer. It sends power through cables to the motherboard and other components. If you decide to open the computer case and take a look, make sure to unplug the computer first. Before touching the inside of the computer, you should touch a grounded metal object or a metal part of the computer casing to discharge any static buildup. Static electricity can be transmitted through the computer circuits, which can seriously damage your machine. Expansion cards Most computers have expansion slots on the motherboard that allow you to add various types of expansion cards. These are sometimes called PCI peripheral component interconnect cards. |
Static electricity can be transmitted through the computer circuits, which can seriously damage your machine. Expansion cards Most computers have expansion slots on the motherboard that allow you to add various types of expansion cards. These are sometimes called PCI peripheral component interconnect cards. You may never need to add any PCI cards because most motherboards have built-in video, sound, network, and other capabilities. However, if you want to boost the performance of your computer or update the capabilities of an older computer, you can always add one or more cards. Below are some of the most common types of expansion cards. Video card The video card is responsible for what you see on the monitor. Most computers have a GPU graphics processing unit built into the motherboard instead of having a separate video card. If you like playing graphics-intensive games, you can add a faster video card to one of the expansion slots to get better performance. Sound card The sound card also called an audio card is responsible for what you hear in the speakers or headphones. Most motherboards have integrated sound, but you can upgrade to a dedicated sound card for higher-quality sound. Network card The network card allows your computer to communicate over a network and access the Internet. It can either connect with an Ethernet cable or through a wireless connection often called Wi-Fi . Many motherboards have built-in network connections, and a network card can also be added to an expansion slot. Bluetooth card or adapter Bluetooth is a technology for wireless communication over short distances. It's often used in computers to communicate with wireless keyboards, mice, and printers. It's commonly built into the motherboard or included in a wireless network card. For computers that don't have Bluetooth, you can purchase a USB adapter, often called a dongleTHE MOTHERBOARD Power supplyfor CPUfan24pins ATMountingPete xt PetesMotherboard Definition of the Motherboard A motherboard is the main circuit board inside a computer that connects the different parts of a computer together. It has sockets for the CPU, RAM and expansion cards and it also hooks up to hard drives, disc drives and front panel ports with cables and wires. Motherboard is also known as a mainboard, planar board or logic board, system board, mobo or MB. It links all the individual parts of a computer together and also, allows the CPU to access and control these separate parts. Other than bridging internal components, the motherboard ports also allows you to connect external devices to the computer. |
Motherboard is also known as a mainboard, planar board or logic board, system board, mobo or MB. It links all the individual parts of a computer together and also, allows the CPU to access and control these separate parts. Other than bridging internal components, the motherboard ports also allows you to connect external devices to the computer. Such external devices would include the monitor, speakers, headphones, microphone, keyboard, mouse, modem and other USB devices. Functions of the Motherboard The functions of a computer motherboard are as follows: i. The motherboard acts as the central backbone of a computer on which other modular parts are installed such as the CPU, RAM and hard disks. Ii. The motherboard also acts as the platform on which various expansion slots are available to install other devices interfaces. Iii. The motherboard is also responsible to distribute power to the various components of the computer. Iv. They are also used in the coordination of the various devices in the computer and maintain an interface among them. V. Some of the Sizes in which the motherboards are available are : BTX, ATX, mini-ATX, micro-ATX, LPX, NLX etc.. Types of Motherboards A computer s motherboard is typically the largest printed circuit board in a machine s chassis. It distributes electricity and facilitates communication between and to the central processing unit CPU , random access memory RAM , and any other component of the computer s hardware. There is a broad range of motherboards, each of which is intended to be compatible with a specific model and size of the computer. To comprehend what motherboards are and what they do, we must first examine their various types and specifications. 1. Advanced Technology AT motherboard Due to their larger physical dimensions which can be measured in hundredths of millimeters , these motherboards do not work properly with computers that fall into the category of smaller desktops. A larger physical size makes it more difficult to install new hardware drivers. The power connections on these motherboards are in the form of sockets and plugs with six prongs each. Due to the difficulty in recognizing these power connections, users often have issues while trying to connect and operate them. In the 1980s, motherboards of this sort were all the rage, and they continued to be manufactured far into the 2000s. 2. Standard ATX motherboard ATX is an enhanced version of the AT motherboard that Intel created in the 1990s. |
In the 1980s, motherboards of this sort were all the rage, and they continued to be manufactured far into the 2000s. 2. Standard ATX motherboard ATX is an enhanced version of the AT motherboard that Intel created in the 1990s. Its name means advanced technology extended, and its initials stand for advanced technology. Unlike AT, it is much more compact and enables the associated components to be interchanged. The connection elements have witnessed significant progress and development. 3. Micro ATX motherboardThe length and width of these motherboards, measured in millimeters, are also 244 mm size metrics will differ as per the manufacturer . This motherboard has fewer ports and slots than the Standard ATX board. Users who do not want excessive connections and subsequent upgrades, like adding more RAM, an extra GPU, or other Peripheral Component Interconnect PCI cards, are better suited for this kind of motherboard than others. This motherboard may be installed in any case with enough space to accommodate 244 mm by 244 mm. It can also be installed in larger cases that are compatible with Standard ATX or eXTENDED ATX motherboards. 4. Extended ATX motherboard The dimensions of this motherboard are 344 millimeters by 330 millimeters dimensions will differ with different manufacturers . This motherboard supports a single or a twin CPU configuration and has up to eight RAM slots. Additionally, it has a higher number of PCIe where e is for Express and PCI slots, which may be used to add PCI cards for a wide range of applications. Workstations and servers are both able to use this software. There is sufficient room on all eATX motherboards, making them ideal for desktop computers, thanks to the significant space provided for airflow and the attachment of various components. 5. Flex ATX motherboard These ATX Form Factor mainboards do not enjoy the same degree of popularity as their ATX Form Factor counterparts. They are the ones within the ATX family that are considered the most compact. They were designed to occupy a minimal amount of space and had a minimal price tag. Flex ATX is a modification of mini ATX that Intel created between 1999-2000. It is a motherboard standard. 6. Low-Profile EXtended LPX motherboardIn comparison to previous iterations, this has two significant enhancements. |
4. RAM memory RAM slots connect the random access memory RAM to the motherboard. RAM allows the computer to temporarily store files and programs that are being accessed by the CPU. Computers with more RAM capacity can hold and process larger files and programs, thus enhancing performance. However, RAM contents are erased when the computer is shut down. A computer usually has two RAM slots. However, some computers have up to four RAM slots in the motherboard to increase the available memory. 5. Basic input output BIOS system The BIOS contains the firmware of the motherboard. It consists of instructions about what to do when the computer is turned on. It is responsible for initializing the hardware components and loading the computer s operating system. The BIOS also allows the computer s operating system to interact and respond with input and output devices such as a mouse and keyboard. In some motherboards, the legacy BIOS is replaced by the modern extensible firmware interface EFI or the unified extensible firmware interface UEFI . UEFI and EFI allow the computer to boot faster, provide more diagnostic andrepair tools, and provide a more efficient interface between the operating system and computer components. 6. Chipsets The chipsets of a computer control how the computer hardware and buses interact with the CPU and other components. Chipsets also determine the amount of memory users can add to a motherboard and the type of connectors that the motherboard can have. The first type of chipset is the northbridge chipset. The northbridge manages the speed at which the CPU communicates with the components. It also controls the processor, the AGP video slot, and the RAM. The second type of chipset is the southbridge chipset. The southbridge chipset controls the rest of the components connected to the computer, including communication between the processor and expansion ports such as USB ports and sound cards. 7. Cooling fans The heat generated when electric current flows between components can make a computer run slowly. If too much heat is left to build up unchecked, it could damage computer components. Thus, a computer performs better when kept cool. Cooling fans increase the airflow, which helps to remove heat from the computer. Some elements, such as video adapter cards, have dedicated cooling fans. 8. Adapter cards and expansion slots Adapter cards are integrated into the motherboard to enhance a computer s functionality. Examples include sound and video adapters. The expansion slots allow users to install compatible adapter cards. |
Adapter cards and expansion slots Adapter cards are integrated into the motherboard to enhance a computer s functionality. Examples include sound and video adapters. The expansion slots allow users to install compatible adapter cards. Examples of expansion slots include the peripheral component interconnect PCI slot, the AGP slot which enables the insertion of video cards , the PCI Express serial bus slot, and the PCI-extended slot. 9. CMOS batteryThe CMOS battery is a small round battery found on the motherboard of every computer. It provides power to the complementary metal oxide semiconductor CMOS chip. The CMOS chip stores BIOS information and computer settings, even when powered down. The CMOS battery allows users to skip resetting BIOS configurations, such as boot order, date, and time settings, each time they power on their computer. 10. Storage devices Storage drives store data permanently or retrieve data from a media disk. The storage devices can either be installed in the computer as hard drives or in removable drives that can connect to the computer through the USB ports. Hard disk drives HDD or solid-state drives SSD are computers primary storage drives. Computers with SSDs execute tasks much faster and perform better than HDDs. Users can also use optical drives such as compact discs to store information. 11. Front panel connectors Front panel connectors connect the light-emitting diode LED lights on the front of the case to the hard drive, the power button, the reset button, and the internal speaker for testing. Some USB and audio devices also have LED lights. These front panel connectors are usually plugged into small pins on the motherboard. Although the pins are grouped and color-coded, their layout structure varies depending on the model of the motherboard. 12. Power connector The power connector provides an electric supply to the computer to function as intended. The power supply connector has 20 pins and converts 110-V AC power into -12-Volt, -5-Volt, and 3.3-Volt direct current DC power. Functions of a Motherboard The following are seven functions of a motherboard:1. Manages data flow The BIOS component of the motherboard ensures that the operating system interacts well with input and output devices, such as the keyboard and mouse, to process instructions. This ensures that the data sent to the computer moves as expected to perform the intended purpose. It also manages data flow through its USB ports, allowing for data transfer between devices.

Data bus 3. Control bus The buses connect the CPU microprocessor to each of the memory and I O devices. The CPU is involved in sending or receiving information to or from memory location, input or output device, and a secondary memory device FDD or HDD . When the CPU sends data to a device or memory, it is called WRITE operation and when the CPU receives data it is called READ operation. The functions of buses are described now. Address Bus The address bus is unidirectional, information flows over it only in one direction, from the CPU to the memory or I O devices. The CPU generates addresses on the lines of the address bus. Each of the addresses corresponds to one memory location or one I O device. When the CPU wants to communicate with READ or WRITE , a certain memory location or I O device, it places the appropriate address on its address output. This address is then decoded to select the desired memory location or I O device. This decoding process usually requires address decoder circuits. Microprocessor local buses Data Bus The data bus is bidirectional and data can flow to the CPU through it. The data bus can be either input or output depending on whether the CPU performs a READ or a WRITE operation. During READ operation the data bus receives data that has been placed on the data bus by memory or I O device selected by the address. During WRITE operation the data bus acts as the output and places data on the data bus which are sent to a selected memory location or I O device. Control Bus The control bus consists of a set of signals that are used to synchronize the activities of separate microcomputer elements. Some of these control signals are sent by the CPU to the other components to tell them the type of operation in progress. The I O devices can send control signals to the CPU. Read Write, Rest, and interrupt are examples of control signals used in a microcomputer. Other busesCOMPUTER MONITOR OR VIDEO DISPLAY UNIT TYPES, AND FEATURES VDU 1. Short for visual display unit, VDU is an any device used with computers to display text and images. For example, a flat-panel display and a projector are both examples of VDUs. However, VDU most commonly describes the CRT cathode ray tube monitor, a now archaic standard replaced by flat-panel display methods like LED lightemitting diode . Early VDUs had a 13" screen size. |
For example, a flat-panel display and a projector are both examples of VDUs. However, VDU most commonly describes the CRT cathode ray tube monitor, a now archaic standard replaced by flat-panel display methods like LED lightemitting diode . Early VDUs had a 13" screen size. By the mid-1990s, 15" and 17" VDU screen sizes became more common, with some 20" screen sizes being released. By the early 2000s, flat-panel monitors with 15" and 17" screen sizes gained popularity and started replacing CRT monitors. 2. Short for video display unit, VDU is a computing device that allows input from a user and output to a display, like a computer monitor. A VDU consists of a display device and a keyboard and could include a mouse. In the United States, it is sometimes known as a video display terminal or VDT video display terminal . Please note The computer monitor is an output device that is used to display softcopy data that is processed on the system unit. A computer monitor is also known as a screen or Visual Display Unit VDU . Some types of computer monitors are CRT, LCD, TFT, Plasma, OLED, LED, touch screen, and curved screens. To acquire a new computer screen, some of the features to consider are resolution, size, technology, refresh rate, video connector, aspect ratio, and viewing angle among other factors. Types of Computer monitors Computer monitors have evolved from the bulky big Cathode Ray Tube monitor to the ultra-slim curved screen that we have today. Some of the computer monitor types that you will find in the market include: 1. Cathode Ray Tube CRT . These are the oldest types of computer monitors and they used the technology of cathode rays. On the back of the screen, there is a cathode gun that shot rays through a vacuum into the screen. The screen has an anode and material that glows when hit by the electrons. The rays hit the glowing material and the image is created appropriately. The monitor had a long back side because the front and cathode gun had to be at a distance for it to give the best results. 2. Liquid Crystal Display LCD . They used the crystal liquid which is easy to be manipulated and changed when light strikes it. Compared to CRT they are lightweight, slimmer, and use less power. 3. |
They used the crystal liquid which is easy to be manipulated and changed when light strikes it. Compared to CRT they are lightweight, slimmer, and use less power. 3. Light emitting diode LED It uses the light-emitting diode as the backlight which makes it slim because it doesn t need the distance that is required in CRT. They produce images with high resolution, are slimmer, less bulky, and produce less heat and less power. 4. Organic Light Emitting Diode OLED It is the latest technology an improvement from LED but still very expensive to produce in bulky. It has an organic substrate that glows when electricity is passed through it. They use less power and they are even slimmer because they don t need backlight since the substrate can produce light. 5. Touchscreens monitors Currently, computer screens are manufactured to take instruction from the human touch. An operating system such as Microsoft Windows 8 and above versions was developed to support a touch screen operation. There are 4 main technologies used for touch screens. A. Capacitive touch screen These screens use the capacitor concept which stores charge. Since the human body has electrical charges when you touch the screen at a specific position you discharge that particular point. The information is then sent to the processor which interprets what needs to be done. They are mostly used on smartphones in today s applications. B. Resistive touch screen The resistive screen uses the concept of resistors where it has two layers with a gap between them. For it to be effective the user has to press and not just touch because the two layers must make contact at the point where it has been pressed. When it is pressed the point can be identified and interpreted appropriately. These touch screens can be touched with a finger and any other objectthat can exact pressure and not a must that it has electrical changes. C. Infrared touch monitors They have an infrared emitter and receiver which create an invisible grid of rays. When you touch the screen you disrupt the ray transmission which is then recorded as a touch. D. Surface acoustic wave monitor These touch screens use sound waves to detect the touch. They have transducers and receivers on the opposite corners of the screen. When you touch the screen you disrupt the sound wave which is sensed as a touch command. 6. Plasma display panel They are flat-panel types of screens made up of small cells containing plasma. Plasma contains charged particles ions and electrons . |
6. Plasma display panel They are flat-panel types of screens made up of small cells containing plasma. Plasma contains charged particles ions and electrons . When electricity is passed through them they emit light which forms an image. They are not common computer screens because they are more economical for big-size screens. 7. Curved computer monitor These are replacing flat screen monitors by offering a curved viewing screen. They offer a better viewing angle compared to a flat screen Factors to consider when choosing a good computer monitor1. Resolution: It is the number of pixels that can be displayed per inch of the screen. The higher the number the more clear the image that is displayed. 3. Aspect ratio: It is the ratio of the length horizontal and width vertical of the monitor. It determines how the image will be stretched on the screen. The main ratios are 4:3 and 16:10. 4. Viewing angle: It is the angle where you can view the image without distortion. CRT screens had a wide viewing angle than LCD screens. 5. Power consumption: LCD uses the least power compared to CRT and OLED type of technology. Less power means power is conserved and also it reduces overheating. 6. Technology: screen comes from different technology modes as discussed in different types above. The technology will determine the image quality, cost, and user preference. 7. Connector video input: latest video connector for monitors is HDMI. However, to be on the safe side you should have a computer screen that supports more than one way of connecting. If you are buying a screen for an already existing system unit make sure you check which is a compatible type of supported connection. 8. Ergonomics: most users spend more time on the screen and would like to get a screen design for comfort. Select a screen that has height adjustability, and can change screen brightness and contrast among other designs. 9. Refresh rate: this is the rate at which the screen can refresh the displayed image per second. A higher refresh rate means the image will be clear and it will not look like it hangs. It is measured in hertz and the higher the better. Most computer screens have 144Hz. 10. Contrast and brightness: contrast ratio is how dark the black part is and how bright the white parts of an image can get. While brightness is the measure of light that the screen can produce. 11. Built-in speakers: latest monitor come with an inbuilt speaker that can be used to complement the system unit speakers. |
While brightness is the measure of light that the screen can produce. 11. Built-in speakers: latest monitor come with an inbuilt speaker that can be used to complement the system unit speakers. 12. USB port: USB port is a common connector interface in today s devices including screens. They can be used to load data without even connecting to the system unit. For future improvement and use, you can select a monitor that has a USB port. Types of computer screen connectors Every computer offers a connection port that allows the computer monitor to be connected to the system unit so that it can receive data being transmitted. Most monitors are connected using a VGA cable. The cable connects the VGA card which translates the information from the system unit into images and text that the user can be able to view. Other screen connectors are AUX, HDMI, DVI, and Display Port. Structure of Visual Display Unit The structure of a Visual Display Unit VDU can vary depending on the specific type of device, but most VDUs have several key components in common. Here is a general overview of the structure of a VDU:1. Display panel: This is the part of the VDU that actually displays the visual information. It is typically made of a thin layer of crystal or plastic, and can display images using a variety of technologies, such as liquid crystal display LCD or organic light-emitting diode OLED . 2.

EXAMPLES OF VDULCD vs LED Displays: The Differences When it comes to choosing between LCD and LED displays, the decision can often be confusing. At first glance, they may seem identical, but there are key differences in their construction, performance, and energy efficiency. In simple terms, LED displays are a type of LCD with a unique backlighting system, and they tend to offer better image quality and power efficiency than standard LCDs. LCD Displays LCD, which stands for Liquid Crystal Display, utilizes a panel of liquid crystal molecules to create images. These molecules twist and untwist to control the amount of light passing through them. However, they do not produce light on their own. Instead, they use a separate backlight or reflector to illuminate the liquid crystals. The backlight in traditional LCD panels is often a Cold Cathode Fluorescent Lamp CCFL . |
However, they do not produce light on their own. Instead, they use a separate backlight or reflector to illuminate the liquid crystals. The backlight in traditional LCD panels is often a Cold Cathode Fluorescent Lamp CCFL . While these displays offer good image quality, they have some limitations. Generally, they consume more power and are bulkier than their LED counterparts. Moreover, they may not provide as high contrast or as vibrant colors. LED Displays LED, or Light Emitting Diode displays, are essentially a type of LCD display. The key difference lies in the backlighting system. Instead of using CCFL, LEDdisplays use tiny light-emitting diodes to illuminate the liquid crystals. This change in lighting source opens up a range of benefits. Firstly, LED displays are more energy efficient. LEDs consume less power than CCFL, making them a greener choice. Secondly, they allow for a slimmer and lighter design, making them ideal for modern, sleek devices. One of the critical advantages of LED displays is the potential for greater picture quality. In LED displays, the diodes can be dimmed or brightened individually. This feature, known as local dimming, enhances the contrast ratio, making blacks appear deeper and whites brighter. Consequently, images are more vibrant and lifelike. PRINTERS Different Types of Printers and Their Functions: What Are the Types of Printers? Thermal Transfer Printers Thermal printers use heat to create an image on special thermal paper. They provide direct thermal and thermal transfer, and they re commonly used in receipt printers, shipping label printers, and fax machines. Additionally, they re fast, quiet, and don t require ink or toner. However, the print quality of a thermal printer may fade, and the paper can be expensive. Dye-Sublimation PrintersDye-sublimation printers use heat to transfer dye onto special paper or other materials like fabric or plastic. They re popular for high-quality photo printing and creating customized items like mugs and T-shirts. Additionally, they produce vibrant, long-lasting prints with excellent color accuracy, but the cost of consumables ink and paper can be relatively high. And they re not ideal for standard office documents. 3D Printers 3D printers create three-dimensional objects by layering material often plastic on top of itself based on a digital 3D model. |
The best part? UV printing offers vibrant colors and durability on various surfaces. However, initial equipment costs can be high, and maintenance may be needed to keep the printer functioning optimally. Digital Presses Digital presses make a great choice for commercial printing and publishing. They re high-volume printing machines suitable for large quantities of books, brochures, and other printed materials. They offer fast, consistent, high-quality printing for large print runs. However, they re expensive and may require specialized training to operate effectively. In summary, there s a wide array of printers, each designed for specific purposes and printing needs. Choosing the right printer depends on the type of documents or images you need to print, the printing volume, and your budget. Consider your requirements carefully to select the printer that best suits your needs, whether for everyday home use, office tasks, creative projects, or industrial applications. Other Types of Printers 9. Plotters HP 9862A Calculator Plotter Example: HP Design Jet T210 A plotter prints vector graphics by drawing lines on paper using a pen. Some plotters use markers to draw multiple, continuous lines onto paper, while some use knives to cut a material like leather or vinyl. The latter is called cutting plotters. These devices have been phased out by computer-controlled printing machines. However, cutting plotters are still used in many industries. Pros Prints on large sheets of paper with high resolution Draws a single pattern more than one thousand times with no degradation Works with various materials, including cardboard, plywood, plastic, and aluminum Cons Expensive and larger than a conventional printer 8. Impact Printers The impact printer physically presses an inked ribbon against the page. Its plastic or metal head strikes the ink ribbon, whereby the ribbon is pressed against the page, and the specific character impression is printed on the paper. Although this mechanism is quite old, impact printers are still widely used in workplaces and industries. Many different types of impact printers have been developed to date. The most common ones are:8.1 Line Printers IBM 1403 line printer Example: Printronix P7-1500N line matrix printer As the name suggests, Line printers print one line of text at a time the full width of the page . They use a continuous feed of paper instead of individual cut sheets. And they can print up to 2,500 lines per minute. |

They use a continuous feed of paper instead of individual cut sheets. And they can print up to 2,500 lines per minute. Pros High-speed printing More durable Low operating costs Consumables are less harmful to the environment Cons Low print quality and cannot print graphics Very noisy, requires sound-absorbing cases 8.2 Dot Matrix Printers Epson LX310 Example: Tvs MSP 250 In a dot matrix printer, the pins are arranged in one or multiple vertical columns. The print head which contains several pins moves up and down or in a back and forth motion and prints by striking an ink-soaked cloth ribbon against the page. This is just like a typewriter, but it can also print arbitrary patterns and not just particular characters. A character printed by a dot matrix printer is actually an accumulation of multiple dots on a very small region of the paper. The printer can be used for text, multiple fonts, and basic graphical printing. The outputs, however, have a dotted appearance. Pros Low printing cost Reliable Prints on multipart forms or carbon copies Useful for data logging Cons Slow speed Limited print quality They can be used to print multiple copies at the same time with the help of carbon copying. Thus, they are widely installed in offices and shops where multipart forms are required. 8.3 Daisy Wheel Printers The daisy wheel and print head on a Diablo D-25 printerExample: Commodore DPS 1101 A daisy wheel printer contains a disk and attached extension on which molded metal characters are mounted. When printing, the printer rotates the disk to each character and strikes it into an ink ribbon to create characters on paper. Pros Can use heavy paper grades and fan-fold paper Can create carbon copies Low costs and maintenance Cons Slow speed Low print quality 7. Minilab Printers SureLab D870Example: Epson Sure Lab D1070DE Minilabs are small photographic-developing and printing systems that are used in several retail stores to provide quick photo finishing services. |

Minilab Printers SureLab D870Example: Epson Sure Lab D1070DE Minilabs are small photographic-developing and printing systems that are used in several retail stores to provide quick photo finishing services. A minilab machine is made of two systems: a film processor and a printer paper processor . Pros Perfect for photo processing High-capacity ink packs Prints on double- or single-sided sheet media Provides better exposed, color-corrected prints in less than 30 minutes Cons Quite pricey Larger and bulkier and than typical printers The Agfa and Kodak minilab machines use C41b chemistry to process films and RA-4 chemistry to process the paper. Depending on the device capabilities and operator s expertise, films can be ready for collection within 20 minutes. 6. Thermal PrintersF2C portable thermal printer Example: Polono Label Printers A thermal printer is made of three components: Thermal head: Generates heat to produce an image on the page Platen: A roller that moves the page Spring: Holds the printhead and paper together by applying small pressure The printer passes paper with a thermochromic coating over a print head. This print head contains several electrically heated elements, typically arranged as a line of small, closely spaced dots. The coating on the paper turns black in the region where it is heated, generating an image. These printers can have a resolution of up to 1,200 DPI. Although most of them print black and white monochrome text, some produce twocolor images. Due to decent print quality, speed, and portability, thermal printers are widely used in the banking, retail, grocery, healthcare, and airline industries. Voucher printers in slot machines, information kiosks, and point of sale systems are some of the commercial applications of these printers. |

Due to decent print quality, speed, and portability, thermal printers are widely used in the banking, retail, grocery, healthcare, and airline industries. Voucher printers in slot machines, information kiosks, and point of sale systems are some of the commercial applications of these printers. Pros More quiet and faster than dot matrix printers Easier to use as there is less use of software involved Requires less maintenance Comes in various models and sizes Cons Prints fewer colors The high heat limits wax and resin choices They are also used to generate sub-seafloor seismic imagery and print real-time records of side-scan sonar. In the data processing field, they are used for quickly creating hard copies of continuous hydrographic or seismic records. 5. Dye-sublimation PrintersTexart RT-640 Example: Texart XT-640 High-Volume Dye-Sublimation Printer Dye-sublimation printers utilize heat to transfer dye onto materials like card, paper, fabric, or plastic. They use the CMYO cyan, magenta, yellow, over coating system to deposit the ink on the surface one color at a time. The ink is deposited via a heat press, which ultimately changes from solid to gas hence the name sublimation and enters the material. The process is carried out at lower temperatures and higher pressures. Small heating elements on the print head change temperatures quickly to lay different amounts of dye. Polyester and polyester resin-coated substances are the perfect materials for this printing technique. Pros Allows printing on rigid surfaces Print thousands of colors using four-color ink CMYK Best for creating ID cards and photographic prints Short learning curveCons The item may lose color over the months Specific type of ink is required Professional and consumer dye-sublimation printers are developed for creating photographic prints, ID cards, license plates, etc. And since these printers are available in various sizes and styles, consumers can print on various products like mouse pads, coffee mugs, handbags, smartphone cases, dresses, pillows, and more. 4. Solid Ink Printers Example: HP Laserjet M209DW As the name suggests, these printers use solid ink instead of fluid ink or toner powder. |
And since these printers are available in various sizes and styles, consumers can print on various products like mouse pads, coffee mugs, handbags, smartphone cases, dresses, pillows, and more. 4. Solid Ink Printers Example: HP Laserjet M209DW As the name suggests, these printers use solid ink instead of fluid ink or toner powder. The printer melts the ink which is usually a waxy resinbased polymer to print images on paper or any substrate. This is how the process goes: small pucks or spheres of solid ink are stored in a hopper. From there, they are transferred to the printhead and melted as per the requirement. Pros Provides precise prints with bright colors Can print on many different types of media Less waste generated compared to inkjet or laser printers Suitable for intermittent use with long periods of downtime Cons The printer need to pause and reheat in between prints Ink may clog printhead nozzles This type of printer can create large graphic images with bright and vivid colors at reasonable costs. It is suitable for users who always have to print in color and require high-quality images. And since the solid ink doesn t dry out over time, you don t have to order new cartridges when you need to print something after a long time. 3. 3D PrintersPrusa I3 MK3S Example: Tronxy X5SA Pro 3D printers are based on a technique called additive manufacturing. They create a physical three-dimensional object from a CAD computeraided design or digital model. It involves adding materials such as powder grains or composites or bio-materials layer by layer at the millimeter scale. Unlike injection molding and CNC machining that uses various cutting tools to make objects, 3D printers require no cutting tools. They construct objects directly onto the built platform. Pros Enables fast design and production Gives you the flexibility to create anything that fits within its build volume Minimize waste Cost-effective Cons Not yet versatile enough to work with most materials Requires post processing Depending on the type of printer, material used, and size of the object, a print takes several hours to complete. The finished object often requires post-processing like sanding, paint, or other conventional finishing touches to achieve the desired surface finish. 3D printing processes can be categorized into 7 groups: 1. Vat photo polymerization 2. |
The finished object often requires post-processing like sanding, paint, or other conventional finishing touches to achieve the desired surface finish. 3D printing processes can be categorized into 7 groups: 1. Vat photo polymerization 2. Material Extrusion 3. Sheet Lamination 4. Directed Energy Deposition 5. Material Jetting 6. Binder Jetting 7. Powder Bed Fusion Modern 3D printers are advanced enough to create complex structures and geometries that would be otherwise impossible to build manually. They can be used to build a range of objects, from simple prototypes to intricate final products, such as medical instruments, aircraft parts, ecofriendly buildings, and even artificial organs using layers of human cells. 2. Liquid Inkjet PrintersHP Smart Tank 530 Example: Canon PIXMA G3260 The inkjet printer creates an image by propelling droplets of ink onto paper or plastic substrates. Its print head moves back and forth as the paper feeds through rollers. The complete image is made of thousands of minuscule dots, like the pixels on a television screen. These dots are extremely small between 50 and 70 microns in diameter and positioned very precisely with resolutions up to 1200 x 1440 DPI. Also, these dots can have multiple colors combined together to produce high-quality pictures. Pros Quieter than impact printers Practically no warm uptime Really good at producing natural shades and colors Easy to set up and use Cons Liquid ink can dry out when stored for a longer period of time Expensive ink refillsLiquid inkjet printers perform best on nonporous paper and slightly heavy bond paper with a hard surface that effectively prevents colors from bleeding. They are available in many different varieties and sizes, ranging from small cost-efficient consumer models to expensive professional machines. While most home inkjet printers are lightweight and have low per-page costs, commercial machines are larger and print on a broader range of materials. 1. Laser Printers Pantum M6602NW Example: HP OfficeJet 5255 Laser printers have become a common consumer product, often used along with personal computers. Their working principle involves electrophotographic, which is the same technique used in photocopy machines. To create a high-quality image, the laser printer continuously passes a laser beam back and forth over a photoreceptor drum. This drum is nothing but a negatively charged cylinder. |
Their working principle involves electrophotographic, which is the same technique used in photocopy machines. To create a high-quality image, the laser printer continuously passes a laser beam back and forth over a photoreceptor drum. This drum is nothing but a negatively charged cylinder. It collects positively chargedpowdered ink toner and transmits the image to paper. The paper is then slightly heated to permanently fuse the image onto it. The standard resolution in most laser printers is 600 DPI, whereas the high-end production machine can have a resolution of 2,400 DPI. Plus, they can print at a much faster rate than inkjet printers. A high-end model can print about 12,000 monochrome pages per hour or 6,000 colored pages per hour. However, they don t print color photos as well as inkjet printers do. That s why most photographers and designers prefer inkjet printers for gallery-quality photos. Pros Fast printing speed Noiseless Produces high-quality monochrome prints Mechanical components are reliable and durable Cons High initial investment cost Not suitable for high quality graphics Laser printers are well suited for office use due to their capability to quickly print large amounts of documents. Overall, they are excellent for text, documents, and printing medium-quality color photos1.1 LED Printers OKI MC853dn Example: Xerox VersaLink C7000DN LED light-emitting diode printers are generally grouped with laser printers because they use a similar technique for creating text or graphics. Both use a toner, drum, and fuser to provide high-quality prints. However, LED printers have an array of light-emitting diodes instead of a laser and mirror. Since LED printers contain fewer moving parts, they are more reliable and efficient than traditional laser printers. Plus, they are cheaper to manufacture and less prone to mechanical wear. Pros Contains fewer moving parts Inexpensive and reliable Noiseless Provides excellent image quality Cons High initial cost Slower printing speed than laser printersFactors to consider when selecting a printer Choosing the best printer can be overwhelming with so many options. To help you decide which type of new printer you should buy, consider the following factors and your specific needs: Printing Purpose Home Use: If you need a printer primarily for occasional home use, like printing documents, school assignments, or family photos, an inkjet printer should suffice. |

First we ll tell you what RAM memory alternatively referred to as main memory, primary memory, or system memory, Random Access Memory RAM in a computer system, it is also sometimes known as read-write memory or RWM, then we ll go over how RAM works in Macintosh s and pcs. Also, there are different kinds of RAM, including VRAM, PRAM, DRAM and SRAM . Random access memory RAM This is the most common type of main memory. It is called random access memory RAM because ; its content can be read directlyregardless of the sequence in which it was stored. As opposed to ROM, the content in RAM is held temporarily and its content is lost once the computer is turned off. Characteristics of random access memory RAM are: 1.Data can be read retrieved and written stored in it. 2 .RAM is a temporary volatile storage because its content disappears when the computer is switched off. 3.Its content is user defined i.e. the user dictates what is to be contained in the RAM. Types of RAM There are two types of-RAM namely, static RAM SRAM and dynamic DRAM .Static RAM is very fast compared to dynamic RAM and holds its content as long as there is power. Dynamic RAM on the other hand can only hold its content for a short while even when power is all .To maintain the content of dynamic RAM, the memory chip is designed in away that its content is refreshed automatically rewritten severally per second. Static RAM is more expensive. It is mostly used to make special types of memories. Special purpose memories Apart from ROM and RAM there are several types of special purpose memories found inside the CPU or in the input and output devices. These memories are vital because they increase the overall performance of data and instructions moving in and out of the CPU. These memories include buffers, registers and cache memory. Buffers This is a temporary holding place that may be part of the CPU or built in an input or output device. Because the CPU is very fast compared to the input or output devices, buffers provide temporary storage so that the CPU is set free to carry out other activities instead of waiting for all data to be entered or information to be output. For example since a printer cannot work at the speed of a CPU, the printer buffers temporarily holds the output to be printed hence freeing the CPU to perform other functions. Buffers can hold more than one piece of data at a time. |
GRADE 8 RATIONALIZED AGRICULTURE AND NUTRITION LESSON NOTESSTRAND 1-CONSERVING AGRICULTURAL ENVIRONMENT1.1 -Soil Conservation Measures. Soil conservation measures refers to a combination of practices done or taken to prevent the loss of soil through soil erosion. Reasons Importance for Soil conservation. To keep top soil in its place. To maintain fertility in the soil. To maintain soil productivity. Helps to increase agricultural production promotes food security. Methods of soil conservation in agricultural environment. Strip cropping. Grassed water ways. Stone lines. Trash lines. Soil bunds. A. Strip cropping. It is the growing of crops in a way that crops that have little soil cover like maize are grown in alternating strips with those that have good ground cover such as sweet potatoes. Permanent vegetation such as grass can also be used as strips. The role of strip crop is it prevents loss of soil through surface runoff. B. Grassed water ways. Grassed waterways are natural or man-made shallow channels in which excess rain water flows. Grass and other vegetations are planted to grow in the channels. When surface run off is directed in the channels, the vegetation in the channels lower the speed of run off and also traps eroded soil. C. Stone lines. These are stones of different sizes heaped in a line along the contour to prevent loss of soil down the slope through run off. Stone lines reduce speed of run off increasing water infiltration especially in semi-arid areas. Water infiltration is the downward entry of water into the soil from the surface. Stone lines are suitable in gently slopes. D. Trash lines. Trash lines are plant materials or crop residues remains arranged along the contour in a cultivated field. Trash lines help to reduce runoff hence preventing loss of soil from land. They also increase water infiltration into the soil. Trash line should be 1 m wide and 0.5 m high. E. Soil bunds. A bund refers to a heap of compacted soil made along the contours. Grasses can be grown on top of the bunds to hold soil together firmly. Bunds help to reduce the volume of water flowing downwards in a cultivated field after rain fall. Bunds enhance water infiltration. NOTE:Most structures constructed to conserve the soil are made along the contour line. Therefore, it is very important to establish the contour lines first before construction of the structures. |
Bunds enhance water infiltration. NOTE:Most structures constructed to conserve the soil are made along the contour line. Therefore, it is very important to establish the contour lines first before construction of the structures. Contour lines are established to guide the position of the soil conservation measures. Contour farming is the farming carried out across the slope rather than up and down. Therefore, contour lines run across the slope and not up and down. A farm layout is a drawn plan that shows various farm enterprises and where they are placed in the farm. A farm layout is a plan of how various farm components enterprises are arranged and set up on the farm. A farm model guides the farmer to locate various farm activities and structures for convenience. What is the importance of Farm layout? It helps in maximum utilization use of land. Farm enterprise are orderly arranged. Local available material that can be used to make a farm model in school include: Cartons. Cardboards. Soil. Papier mache. 1.2 -Water Harvesting and StorageIn rainy season, a lot of water goes in waste. This water can be harvested and stored then used for farming purposes. Methods of harvesting and storing water for farming purposes. There are various methods used to harvest and store water for farming purposes. Use of rooftops. Use of diversion channels. Directs water into water ponds and water tanks. Water ponds. Shallow water pans. Tanks. Shallow water pansGrass should be planted around the shallow water pan to:Control soil erosion. Control sedimentation. Constructing Shallow water pan. Measure desired size of the structure. -. Dig out soil to the desired length and width with depth between 1 to 3 metres. Make conveyor or small channels that directs surface runoff to the structure. Water pondConstruction of a water pond. Mark desired measurements on ground. Dig out the soil. Place a polythene liner evenly covering the sides and the base. Reinforce the liner by placing soil in the upper part around the pond. Plant grass around the pond to control erosion and sedimentation. Make channels to transfer surface runoff. Water tanks. Water tanks can be used to collect surface runoff or water from the rooftops. Ensure water flow into the tank by removing any materials such as gravel, sediments from the sieve entrance of the tank. Gutters should be fixed around the house to collect water when it rains and direct it to the tank through pipes for storage. |

Gutters should be fixed around the house to collect water when it rains and direct it to the tank through pipes for storage. Underground water tank Elevated water tankFactors to consider when setting up a water harvesting and storage unit at home or at school. Location. Accessibility. Type of crop to be irrigated using water. Size of the farm. Dimension of the storage unit. The slope of the land. The cost of the work. Importance of harvesting and storing water. Harvesting and storing water helps to supplement other sources of water. It provides water during shortage and in dry seasons. Water is available through out. Reduces cost of farming. Excess water from the rain is utilized. Helps to prevent destruction of infrastructures such as buildings and roads by surface runoff. Maintenance of water harvesting and storage structures. Plant grass around the water pans and water ponds to control soil erosion and sedimentation and to stabilize the embankments. Remove foreign material in water found in water pans, ponds and tanks. Structures such as water pans and water pons should be fenced. Water tanks should be cleaned and foreign materials such as gravel, twigs, leaves sieved out during water entry. Clean the gutters to remove accumulated materials. Uses of water harvested and stored on the farm. Watering irrigating crops. Watering animals. Domestic uses such as washing, cleaning items etc. Types of water storage tanks. Water tanks can be:Plastic. Metallic. Concrete. They can also be elevated placed on top of the ground or underground. STRAND 2- FOOD PRODUCTION PROCESSES2.1 Kitchen and Backyard Gardening. Food security is an important aspect of a healthy society. To promote food security, household should embrace kitchen gardens. A kitchen garden ensures regular and ready supply of fresh vegetables, fruits and herbs. Food security exists only when all people at all times have access to sufficient, safe and nutritious food that meets their dietary needs and food preference for healthy living. Kitchen garden is any convenient size of a plot, space or structure located in a home where a variety of crops are grown mainly for family consumption. The role of a kitchen garden in food and nutrition security. To produce safe, fresh food that is accessible to the family. |
Kitchen garden is any convenient size of a plot, space or structure located in a home where a variety of crops are grown mainly for family consumption. The role of a kitchen garden in food and nutrition security. To produce safe, fresh food that is accessible to the family. It is a reliable source of green leafy vegetables, herbs, fruits, legumes and cereals for home consumption. Growing of both seasonal and off-season crops that ensures steady supply of nutritious food. Help family to meet their nutritional needs and promotes healthier lifestyles. Generates income from sale of surplus excess produce. Helps to save family income direct towards purchase of vegetables, fruits and others. Provide alternative when staple foods are not in stock. Helps to increase food production. Some form of kitchen gardening use recycled materials like plastics hence contributes to environmental conservation. Innovative technologies for kitchen garden. Increase in population and urbanization has led to limited space that can be used to establish large gardens. Innovative technologies ensure proper use of the small available space for maximum production. The main aim of innovative gardening is to maximize the small available space with proper water conservation, measures in crop production. Examples of innovative kitchen gardens include:Container. Wick. Hanging pots. Tyre. Multistore gardens. Simple drip. Organic sack garden. Most of the kitchen gardens focus on vertical gardens which keeps the crops off the ground as compared to horizontal gardening. Benefits of innovative gardens. Use locally available materials. Requires little amount of water. Easy to manage because less labour is required. Makes good use of little space. Some are portable-can be moved from one area to another. High productivity or yields. Aesthetic value around the compound. Ideal for urban areas and congested homesteads. 2.2 Poultry Rearing in a Fold. Poultry rearing is the keeping of domesticated birds such as chicken, ducks, turkeys, geese, pigeons, guinea fowls and ostriches. Poultry are kept for production of meat, eggs and other products. Poultry folds. Structural appearance of a poultry fold. A fold is a portable structure used for rearing poultry in an open piece of land where they can access sunlight, vegetation to supplement their feeds and can also exercise. Feed and water troughs are placed inside the folds. The fold can be moved from one place to another for the birds to eat fresh vegetation. Poultry folds are portable triangular shaped structures. |
Feed and water troughs are placed inside the folds. The fold can be moved from one place to another for the birds to eat fresh vegetation. Poultry folds are portable triangular shaped structures. A fold has two sections, one is roofed and the other is left open but fitted wih wire mesh to secure the birds. The fold has a door fitted on one side. Materials used in the Construction of a poultry fold. Poultry folds are constructed using locally available materials. This makes it cheap and easy to construct them. Materials for constructing a poultry fold include:NOTE:Smaller folds have rollers and wheels that helps to move them from place to place. Some folds structures have wire mesh at the base to allow droppings to pass through to the ground. Fencing staples can be used instead of nails. The size of the fold depends on the number and type of poultry reared. Rearing practices of poultry in a fold. There are various practices which are carried out when rearing poultry in a fold. These rearing practices includes: Moving the fold to new sites regularly for the birds to feed on fresh vegetation. Ensure birds are provided with clean water. Ensure hygiene is maintained in the poultry fold. The fold should be strong enough to secure birds and kept in a safe place. The fold should be sheltered from the rain to avoid wetness. It should be placed in such a way that the open side is away from direct winds to avoid drought. How to rear Poultry in a fold. Sitting. Where to place your fold Ensure the fold is placed in an area: Protected from rain and direct wind. With enough security. That can be easily accessible. With enough vegetation. Stocking the folds. Place chicks into the fold carefully in the early hours of the day for them to familiarize with the environment. Place the right number of birds in the fold to avoid overcrowding which encourages diseases. Feeding. Provide enough feed depending on the stages of growth. Place feed in the feeding troughs. Move fold unit from one place to another to enable birds to eat fresh vegetation. Watering. Provide clean water in waterers. Sanitation. Maintain high standards of hygiene in the folds by cleaning the waterer, feed troughs and poultry folds. Vaccination. |
How fresh fish is processed. Fresh fish need to be processed immediately after being harvested from water to prevent spoilage. Various processes are carried out to prepare fresh fish for transportation, storage and consumption. Fish is prepared after harvesting by:Scaling-removal of scales. Gutting-removal of gut or the alimentary canal. Cleaning-washing the fish with clean water. These processes usually slow down the growth of micro-organisms and keep it fresh before use. Procedure followed when processing fresh fish. Specific methods of processing fish for consumption, storage and transportation are as follows:Inspect and select fresh fish for processing. Start the process as follows. A. Scaling. Rinse fish to remove slime. Place fish on a chopping board or tray with absorbent paper. Hold fish firmly by the tail and use a fish scaling tool or back of a knife to scrape off the scales moving from the tail to head on both sides Rinse the fish in clean water to remove any loose scales. Run your fingers over the fish skin to make sure that all scales have been removed. B. Gutting. Lie the fish on its side on either a chopping board or a tray. Make a cut in the belly of the fish at the tail-end and cut through the skin to the head. Insert your fingers into the belly through the cut opening and remove internal organs by easily pulling them out. Place them on a separate plate or tray. Rinse the inside of the fish with cold water until the water becomes clear. Use a kitchen paper or towel to dry the fish. Cleaning. Clean the fish thoroughly before and after gutting. Use cold water when cleaning fish. Salting. Use the fish that have been well prepared by scaling, gutting and properly cleaned. Place the fish on a flat clean surface or tray where they will remain after salting. Sprinkle layers of salt on all the parts of the fish. Leave the fish in layers of slat for at least 2 days. Keep the salted fish in a cool dry place. Frying fish Select a clean well-prepared fish. Heat oil in a saucepan and dip the fish to cook for 4 to 5 minutes. |
Keep the salted fish in a cool dry place. Frying fish Select a clean well-prepared fish. Heat oil in a saucepan and dip the fish to cook for 4 to 5 minutes. Remove the fish from the oil using a draining spoon. Place the fish on a mesh tray to drain excess oil. NOTE: Processing fish should be carried out in a hygienic environment to prevent contamination. Cold water should always be used when cleaning fish to remove all the blood. This prevents deterioration due to multiplication of bacteria. Gutting fish may sometimes include the complete removal of the gills and the fins. Salting draws water from the fish increasing its shelf life. How to dress poultry carcass. Quality of poultry products can be linked to a variety of factors such as handling at slaughter. Poultry dressing procedures should be done in a hygienic manner in order to produce products fit for human consumption. When dressing poultry carcass, some parts can be detached and packed separately. However, the whole carcass can be packed with the parts attached. Poultry thighs poultry gizzardsDressing a poultry carcass. The following practices are carried out to dress the poultry carcass. Beheading-restrain the poultry well and cut the neck muscles with a sharp knife. Defeathering-scald the bird into hot water of a temperature of 550 C for about 2 minutes to loosen the feather. Remove and pluck off loose feathers completely. Singeing-hold the defeathered bird over a flame for a few minutes to burn the hair like structures left on the skin. Washing-wash the whole bird in clean cold water to remove the surface dirt. Prepare the poultry carcass for various purposes as follows. Place the carcass on its back on a clean surface or chopping board. Remove oil gland with a knife. Remove the offals by:Make a cut above the vent but avoid cutting too deep. Press on the breast and insert fingers through the cut made on the vent. Grab the visceral and pull them out avoiding too much pressures to prevent puncturing the gall bladder. Slit the neck skin to remove the crop, trachea and Oesophagus. Place the internal organs on a separate plate. Cutting the carcass into various pieces. |
Slit the neck skin to remove the crop, trachea and Oesophagus. Place the internal organs on a separate plate. Cutting the carcass into various pieces. Cut joints between thigh and the body and separate the thigh and the leg at the joint. Cut the joint between the wings and the body and then separate the wings. Cut the breast into two parts by separating the muscle in front of the keel. Cut the backbone and neck strip into 3 pieces each. Separate the gizzard, liver and the heart from the other internal organs. Cut open the wall of the gizzard lengthwise to the lining to remove hard grit and then peel out the lining. Wash these organs in cold water and then pack them. Pack all the pieces in clean storage bags as required. NOTES: High hygiene standards should be maintained when handling raw poultry meat to avoid contamination which can lead to food poisoning. Complete bleeding of carcass prevents discolouration of the meat due to formation of clots in the muscles. The clots attract micro-organisms. Care should be taken not to burst gall bladder as this makes the meat bitter. Pieces from poultry carcass are packed separately and sold at different prices. What is the importance of processing fresh fish and dressing poultry carcass? It adds value to the meat. Keeping quality of both fish and poultry products is increased hence prolonged shelf life. Packing poultry pieces separately enables selling at a higher price than the whole carcass. 2.5 Preserving Meat and Milk. Animals gives products such as milk, meat, eggs, honey, hides and skin. Some of the products easily go bad, hence they should be preserved to increase their shelflife. Methods of preserving milk and meat in the locality. Milk and meat deteriorate in quality with time. They should be well preserved to prolong their shelf-life and availability. Food preservation is the process of preventing food from spoilage. There are various methods of preserving milk and meat. Methods used in preserving milk include:Boiling. Fermentation. Methods used to preserve meat include:Sun drying. Smoking. Salting. Preservation of Milk and Meat at household level. Common methods of preserving milk are:Fermentation-Fermentation of milk produces certain acid that preserves milk. Boiling or pasteurization of milk-boiling milk kills micro-organisms by exposing them to high temperatures at the milk boiling point. |
Preservation of Milk and Meat at household level. Common methods of preserving milk are:Fermentation-Fermentation of milk produces certain acid that preserves milk. Boiling or pasteurization of milk-boiling milk kills micro-organisms by exposing them to high temperatures at the milk boiling point. This method preserves fresh milk. Common methods of preserving meat are:Sun drying-it removes moisture from meat making the action of micro-organism difficult. Meat is cut into small pieces, sundried and then packaged. Smoking-meat is covered with a layer of smoke which stops action of micro-organisms. Salting-salt is applied on the surface of pieces of meat or dipped in a highly concentrated salt solution know as brine. This salt solution dehydrates removes water the micro-organisms and stops their action on meat. What is the importance of preserving milk and meat? It increases the shelf-life of both milk and meat. It makes the two products available for a longer period of time hence enhancing food security. Strand 3 -HYGIENE PRACTICES. 3.1-Cleaning the Kitchen. Methods of removing dirt from the kitchen surfaces. Food should be prepared and cooked in a clean and orderly environment. A dirty kitchen can be a breeding place for other harmful living things such as pests and flies which can lead to health hazards. There are may ways of removing dirt from kitchen surface. The methods depend on types of dirt found on the surfaces. Methods of removing dirt from kitchen surfaces. Sweeping-Done using a broom, brush and dustpan. Dusting-it is done after sweeping a room. It ensures any dust that may have been blown in the air and deposited on the surface is removed. Wiping -it is used to remove fixed dirt on the surfaces that can be damaged by scrubbing. Surfaces that are wiped include furniture, ornaments, walls and windows. Scrubbing-this is where warm soapy water is used to together with a hard scrubbing brush. Vacuum cleaning-a vacuum cleaner is used to remove loose dirt from the surfaces which is sucked into a dirt bag attached to the vacuum cleaner and it is disposed of after cleaning. Mopping-this is the removal of fixed dirt from a surface by using a mop, bucket, water and detergents. State the reasons for cleaning the Kitchen. A kitchen must be kept clean at all times. Frequency of cleaning depends on type of fuel used and amount of cooking done. |
State the reasons for cleaning the Kitchen. A kitchen must be kept clean at all times. Frequency of cleaning depends on type of fuel used and amount of cooking done. Therefore, cleaning the kitchen is necessary for the following reasons:To preserve clean kitchen appearance. To prolong life of a surface, dirt can destroy the surface if allowed to accumulate. Psychological satisfaction of the user. To cut down cost of cleaningTypes of leaning for a kitchen. Daily cleaning. It is the removal of loose dirt from the kitchen surfaces on daily basis. It involves the following methods:Sweeping. Brushing. Dusting. Suction cleaning. Weekly cleaning. Involves the removal of both loose and fixed dirt. It involves:Sweeping. Dusting. Scrubbing. Wiping. Special cleaning. This is the thorough cleaning that is done occasionally when it is necessary. For example,Cleaning the chimney to remove soot,Painting the walls. Cleaning different kitchen surfaces. Strand 4- PRODUCTION TECHNIQUEStogether in position with stitches. This has to be done neatly and securely for the item to look presentable and to last long. A seam is any part of the garment or clothing article where two or more pieces of fabric are joined together using permanent stitches. Seam line is also referred to as the stitching line, construction line or fitting line. It is the line where permanent stitches are worked. Seam allowance is the distance between the seam line and the cutting line. It is usually1.5cm wide. Seam turning is the amount of fabric between the cutting line and the seam line. Types of Seams used in clothing construction. There are many types of seams used in clothing construction. The type of seam used depends on the desired outlook and stitching effects required. Open seam. Plain seam. Overlaid seam French seam. Machine fell seam double stitched Run and fell seam. Factors to consider when choosing seams in clothing construction. Type of garment-Frequent laundered garments are preferably made using a plain seam because the turnings of the plain seam are neatened together making it to remain closed during laundering. Type of fabric- heavy fabrics require seams that are not bulky to prevent the seam from becoming too thick, for example, an open seam can be used for heavy fabrics because it is not bulky. Position of the seam on the garment- some seams are more suitable for some areas of garment than others. |

Type of fabric- heavy fabrics require seams that are not bulky to prevent the seam from becoming too thick, for example, an open seam can be used for heavy fabrics because it is not bulky. Position of the seam on the garment- some seams are more suitable for some areas of garment than others. For example, a plain seam is more suitable for the armhole seam as compared to open seam. The effect desired-when a decorative effect is required, seams such as machine fell and overlaid seams that are constructed show on the right side of fabric when used. Qualities of A well-made seam. A well-made seam should have some specific qualities as follows. Should be firmly stitched. Should be accurately stitched on the fitting line. Should be neatly stitched. Should be properly matched where two or ore seams meet. Should be of appropriate width. Should be well-pressed and flat. MAKING SEAMS. The most commonly used seams in garment construction are the open and plain seam. They lie flat when finishing pressed or ironed and can be used in most types of articles. Open Seam. An open seam is a simple seam that has been stitched and pressed open. STUDENT ACTIVITIES GUIDED BY THE TEACHERMaking an open seam. Requirements. 2 pieces of cloth 10 cm by 1o cm . A pair of scissors. Tape measure. Tailor s chalk. Hand sewing needle. Sewing thread. Pins. A table and well threaded sewing machine. Method. I.

Remove the tacking stitches. Press the seam flat on the wrong side. 4.1 Innovative Waterer Project. Water is an essential requirement in animals just like in plants. Animals should drink clean and adequate water every day. Providing enough and clean water is a challenge for human beings and animals. Therefore, innovative economical ways of using available water to take care of domestic animals. Types of animal waterer used by the community. Domestic animals are provided water in containers called waterers. Different domestic animals use different types of waterers. Some waterers are left open for the animals to drink water directly while others are automatic. The types of waterer used for watering animals in the community depends on the type of domestic animals kept. Large animals such as cattle, camel. Donkeys, sheep, goat and pigs use open containers and troughs constructed as part of their houses. Small animals such as rabbits and poultry use small containers cutout from jerrycans and hanged on the walls of their cages. Challenges of the existing animal waterers used by domestic animals in the community. Use of poorly constructed waterers-leads to inadequate water intake by the animals. Lack of skills in handling the waters. Poor placement of the waters. Poor usage by the animals leading to spillage and contamination of water. Provision of water to animals is a tiresome process discouraging community members from keeping domestic animals. Provision of less spacious waterers for large number of animals. |

Containers for any type of chemical should nor be used for waterers, unless they are cleaned thoroughly with detergent before use. Innovative techniques for watering small domestic animals. An innovation means an idea generated in the mind and then created into reality. We can improve the existing waterer in the community to solve the challenges of watering animals or create new better waterer. Different groups can create their own innovations and select the innovation that has less cost. Requirements for functionality of Waterers. Should be workable. Should be easy to use. Should be easy to clean. Should have efficient overflow control system to prevent spillage. Should have a mechanism of adding water easily to avoid time wasting. Should be heavy enough to prevent animals from toppling it off the ground. Provision of Water to animals using the innovative waterer constructed. If waterer are placed at a higher point ,water remain clean for a long time. Waterer contaminated with feeds should be changed immediately. Accidental water spillage increases humid conditions in animals houses and should be controlled. Importance of using innovative waterer in animal rearing. Innovative waterer are made with locally available materials to suit needs of the farmer and of particular animals. They are economical and affordable. They are easy to operate and maintain. 4.3- ICT In Agricultural Support Services. ICT stands for Information Communication and Technology.
