Question

what is cache memory and its importance

Answer 1

Cache memory, also called CPU memory, is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. This memory is typically integrated directly with the CPU chip or placed on a separate chip that has a separate businterconnect with the CPU.

It acts as a high speed buffer between CPU and main memory and is used to temporary store very active data and action during processing since the cache memory is faster then main memory, the processing speed is increased by making the data and instructions needed in current processing available in cache. The cache memory is very expensive and hence is limited in capacity.

Answer 2

Temporary memory in the computer that is automatically created and destroyed is called cache memory. It is useful as it helps a particular program to function properly by creating its small size cache.
