What is the main purpose of cache memory?

Answer and explanation

Correct answer: Provide fast access to frequently used data

The governing concept is the cache hierarchy between the processor and main memory. Cache stores copies of instructions and data that the CPU is likely to use again, so the processor can retrieve them faster than it usually can from RAM. This reduces waiting time and may improve performance; it does not provide permanent backup. Therefore, option A is correct. Printing is an output function, and internet signalling belongs to communication hardware, not cache memory.
