https://en.wikipedia.org/wiki/Anatomy | Anatomy () is the branch of biology concerned with the study of the structure of organisms and their parts. Anatomy is a branch of natural science that deals with the structural organization of living things. It is an old science, having its beginnings in prehistoric times. Anatomy is inherently tied to developmental b... |
https://en.wikipedia.org/wiki/Switch%20virtual%20interface | A switch virtual interface (SVI) represents a logical layer-3 interface on a switch.
VLANs divide broadcast domains in a LAN environment. Whenever hosts in one VLAN need to communicate with hosts in another VLAN, the traffic must be routed between them. This is known as inter-VLAN routing. On layer-3 switches it is a... |
https://en.wikipedia.org/wiki/Grading%20%28tumors%29 | In pathology, grading is a measure of the cell appearance in tumors and other neoplasms. Some pathology grading systems apply only to malignant neoplasms (cancer); others apply also to benign neoplasms. The neoplastic grading is a measure of cell anaplasia (reversion of differentiation) in the sampled tumor and is bas... |
https://en.wikipedia.org/wiki/Charge%20controller | A charge controller, charge regulator or battery regulator limits the rate at which electric current is added to or drawn from electric batteries to protect against electrical overload, overcharging, and may protect against overvoltage. This prevents conditions that reduce battery performance or lifespan and may pose a... |
https://en.wikipedia.org/wiki/Galactic%20algorithm | A galactic algorithm is one that outperforms other algorithms for problems that are sufficiently large, but where "sufficiently large" is so big that the algorithm is never used in practice. Galactic algorithms were so named by Richard Lipton and Ken Regan, because they will never be used on any data sets on Earth.

https://en.wikipedia.org/wiki/Electronic%20hardware | Electronic hardware consists of interconnected electronic components which perform analog or logic operations on received and locally stored information to produce as output or store resulting new information or to provide control for output actuator mechanisms.
Electronic hardware can range from individual chips/circ... |
https://en.wikipedia.org/wiki/Circuit%20underutilization | Circuit underutilization also chip underutilization, programmable circuit underutilization, gate underutilization, logic block underutilization refers to a physical incomplete utility of semiconductor grade silicon on a standardized mass-produced circuit programmable chip, such as a gate array type ASIC, an FPGA, or a ... |
https://en.wikipedia.org/wiki/Mass%20action%20law%20%28electronics%29 | In electronics and semiconductor physics, the law of mass action relates the concentrations of free electrons and electron holes under thermal equilibrium. It states that, under thermal equilibrium, the product of the free electron concentration and the free hole concentration is equal to a constant square of intrin... |
https://en.wikipedia.org/wiki/CoRR%20hypothesis | The CoRR hypothesis states that the location of genetic information in cytoplasmic organelles permits regulation of its expression by the reduction-oxidation ("redox") state of its gene products.
CoRR is short for "co-location for redox regulation", itself a shortened form of "co-location (of gene and gene product) fo... |
https://en.wikipedia.org/wiki/Link%20flap | Link flap is a condition where a communications link alternates between up and down states. Link flap can be caused by end station reboots, power-saving features, incorrect duplex configuration or marginal connections and signal integrity issues on the link. |
https://en.wikipedia.org/wiki/Mail-sink | Smtp-sink is a utility program in the Postfix Mail software package that implements a "black hole" function. It listens on the named host (or address) and port. It accepts Simple Mail Transfer Protocol (SMTP) messages from the network and discards them. The purpose is to support measurement of client performance. It is... |
