Question

Write a short note on Cache Memory PLEASE.

Answer 1

Answer:

Cache memory is a very high speed semiconductor memory which can speed up CPU . It acts as a bufer between the CPU and the main memory . It used to hold those parts of data and program which are most frequently used by the CPU . The parts of data and programs are transferred from disk to cache memory by operating system from where CPU can access them .

Answer 2

A Cache (Pronounced as “cash”) is a small and very fast temporary storage memory. It is designed to speed up the transfer of data and instructions. It is located inside or close to the CPU chip. It is faster than RAM and the data/instructions that are most recently or most frequently used by CPU are stored in cache.
A computer can have several different levels of cache memory. The level numbers refers to distance from CPU where Level 1 is the closest. All levels of cache memory are faster than RAM. The cache closest to CPU is always faster but generally costs more and stores less data then other level of cache.

Level 1 (L1) Cache
It is also called primary or internal cache. It is built directly into the processor chip. It has small capacity from 8 Km to 128 Kb.
Level 2 (L2) Cache
It is slower than L1 cache. Its storage capacity is more, i-e. From 64 Kb to 16 MB. The current processors contain advanced transfer cache on processor chip that is a type of L2 cache. The common size of this cache is from 512 kb to 8 Mb.
Level 3 (L3) Cache
This cache is separate from processor chip on the motherboard. It exists on the computer that uses L2 advanced transfer cache. It is slower than L1 and L2 cache. The personal computer often has up to 8 MB of L3 cache.
