Cache memory _____
Tap an option to check yourself.
Answer: D) Placed between the main memory and microprocessor
Cache memory is a small, very fast memory that sits between the CPU (microprocessor) and main memory (RAM). It temporarily holds frequently accessed data and instructions so the processor can retrieve them much faster than from RAM.
A is incorrect — permanent storage is provided by ROM, hard disks, SSDs, etc. Cache is volatile.
B is incorrect — that describes browser history or web-cache behavior, not CPU cache memory.
C is incorrect — cache does not increase hard-disk capacity; its purpose is speed, not storage size.
