Answer

Computer makes use of two types of memories :

  1. Internal memory (primary or main memory) — It is the built-in memory which the CPU uses to hold data and instructions. The internal memory is temporary and has limited storage capacity.
  2. External memory (auxiliary or secondary memory) — It is the external storage used by computer to store data and instructions permanently. Floppy disks, hard disks, CD ROM, DVDs etc. comprise this memory.
