✔ What do you mean by Cache Memory? ✔

⛔ No spams ⛔

Answer 1

Short note on Cache Memory:

(i) It is a volatile computer memory which resides insides the CPU and helps in  accessing the data and instructions stored in the RAM memory fastly.

(or)

A computer memory that provides high-speed data access to the processor and stores frequently used computer programs, applications etc.

(ii) Initially, the CPU requests the content of memory location to cache. If the data is found in cache,then it will retrieve and process it.This process is called as Cache HIT. If the data is not found in cache, then main memory is accessed then main memory is accessed to read contents/data. This process is called as Cache Miss.

(iii) Levels of cache memory are: L1, L2 and L3.

L1 - Fastest cache.

L2 - Slower in speed compared to L1

L3 - Slower than L1 and L2 cache.

(iv) Advantages of cache memory:

(a) Faster than main memory

(b) Helps in reducing the bottle neck of system bus

(v) Disadvantages of cache memory:

(a) Expensive

Hope this information helps!

Cache memory, also called CPU memory, is high-speed static random access memory (SRAM) that a computer microprocessor can access more quickly than it can access regular random access memory (RAM). This memory is typically integrated directly into the CPU chip or placed on a separate chip that has a separate bus interconnect with the CPU. The purpose of cache memory is to store program instructions and data that are used repeatedly in the operation of programs or information that the CPU is likely to need next. The computer processor can access this information quickly from the cache rather than having to get it from computer's main memory. Fast access to these instructions increases the overall speed of the program.
