Question

what is cache memory?​

Answer 1

Explanation:

cache is a hardware cache used by the central processing unit of a computer to reduce the average cost to access data from the main memory. A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations.

Answer 2

Cache Memory: Cache memory is the small size of RAM inside the processors. This cache memory is SRAM (Static RAM) unlike the DRAM (Dynamic RAM) which we find in normal RAM. This SRAM is quite fast compared to DRAM. In computers, we find different levels of cache memory.
