Explanation:
Detailed explanation-1: -The CPU cache stands at the top of this hierarchy, being the fastest. It is also the closest to where the central processing occurs, being a part of the CPU itself. According to Tech Target, “Cache memory operates between 10 to 100 times faster than RAM, requiring only a few nanoseconds to respond to a CPU request."
