What is cache memory? What is the need of it?

divyansh101dabral: it is a very fast memory, and is a part of the processor itself rather than ram chip

divyansh101dabral: the os can store often used apps on it so they are accessed more quickly

divyansh101dabral: it is part of processor so is much faster than ram

divyansh101dabral: nowadays processors come usually with 6- 12 mb of cache(level 3 cache)

divyansh101dabral: there are three levels of cache memory, lvl 1 being fastest(so more used data is put here) and lvl 3is comparatively slower

Hello frd _/\_

Your Answer - >>

-: Cache Memory :-

Cache memory is a very high speed semiconductor memory, which can speed up CPU. It acts as a buffer between the CPU and main memory.

It is used to hold those parts of data and program which are most frequently used by CPU. The parts of data and programs are transferred from disk to cache memory by operating system, from where CPU can access them.

Advantage : -

• Cache memory is faster than main memory.

• It consumes less access time as compared to main memory.

• It stores the program that can be executed within a short period of time.

•It stores data for temporary use.

Disadvantage : -

• Cache memory has limited capacity.

• It is very expensive
