Which of the following is fastest memory?

Answer: Cache memory is the fastest memory.

Cache memory stores the data that is frequently used by the CPU. It has a faster access time where data is temporarily stored for faster access. It fetches and executes instructions. Level 1 cache is the next fastest form of cache memory located on the CPU itself. The memory that is used for cache memory is Static random-access memory (SRAM).
