In computer programming and software engineering , software brittleness is the increased difficulty in fixing older software that may appear reliable, but instead, fails, when presented with unusual data or data that is altered in a seemingly minor way. The phrase is derived from analogies to brittleness in metalworkin... | https://en.wikipedia.org/wiki/Software_brittleness |
A software calculator is a calculator that has been implemented as a computer program , rather than as a physical hardware device.
They are among the simpler interactive software tools, and, as such, they provide operations for the user to select one at a time. They can be used to perform any process that consists of ... | https://en.wikipedia.org/wiki/Software_calculator |
Software categories are groups of software . They allow software to be understood in terms of those categories, instead of the particularities of each package. Different classification schemes consider different aspects of software.

Software crisis is a term used in the early days of computing science for the difficulty of writing useful and efficient computer programs in the required time. The software crisis was due to the rapid increases in computer power and the complexity of the problems that could be tackled. With the increase in the complex... | https://en.wikipedia.org/wiki/Software_crisis |
Software design is the process of conceptualizing how a software system will work before it is implemented or modified. [ 1 ] Software design also refers to the direct result of the design process – the concepts of how the software will work which consists of both design documentation and undocumented concepts.

Software development is the process of designing and implementing a software solution to satisfy a user . The process is more encompassing than programming , writing code , in that it includes conceiving the goal, evaluating feasibility, analyzing requirements , design , testing and release . The process is part of sof... | https://en.wikipedia.org/wiki/Software_developer |
Software diagnosis (also: software diagnostics ) refers to concepts, techniques, and tools that allow for obtaining findings, conclusions, and evaluations about software systems and their implementation, composition, behaviour, and evolution. It serves as means to monitor, steer, observe and optimize software developme... | https://en.wikipedia.org/wiki/Software_diagnosis |
Software distribution is the process of delivering software to the end user. [ 1 ]
