What is CACHE Memory?

Cache memory is an intermediate form of storage between the ultra-fast registers and the RAM. The CPU uses cache memory to store instructions and data that are repeatedly required to execute programs, thereby improving the overall system speed and increasing the performance of the computer. Maintaining frequently accessed data and instructions in the cache helps in avoiding the need to access the slower DRAM repeatedly.
CACHE memory is widely used for memory caching. Cache memory is basically a portion of memory made of high speed static RAM (SRAM) instead of the slower and cheaper DRAM which is used for main memory.

TIA/EIA 568a and 568b Wiring Color Codes

TIA/EIA-568-B.1-2001 is likely the most commonly used and talked about feature of the specification created in 1988. 568-a is the definition of pin assignments for the the pairs within Category 3 (CAT3), Category 5 (CAT5) and Category 6 (CAT6) unshielded twisted-pair (UTP) cables (eight conductor, 100-ohm balanced twisted pair cabling). The Pin/Pair assignments were named T568A and T568b, both of which define the pinout or specific order the UTP pairs need to be terminated within 8P8C (Eight Position, Eight Conductor) modular connecters, also known as RJ45 connectors. 568-A Color Code Pin #Wire Color 1-White/Green 2-Green 3-White/Orange 4-Blue 5-White/Blue 6-Orange 7-White/Brown 8-Brown 568-B Color Code Pin #Wire Color 1-White/Orange 2-Orange 3-White/Green 4-Blue 5-White/Blue 6-Green 7-White/Brown 8-Brown

What is Motherboard ?

Motherboard is a printed circuit board containing the principal components of a computer or other device, with connectors for other circuit boards to be slotted into.
