Which of these storage devices can act as a buffer between the CPU and the main memory ?

  1. Cache Memory ✓
  2. Floppy disk
  3. Hard disk
  4. Flash drive
Explanation

Cache memory is a small, very fast memory placed between the CPU and main memory. It keeps data the CPU uses often, so the CPU waits less.

Floppy disks, hard disks and flash drives are slow backup storage and cannot do this.
