  • It is a memory unit that improves access speed.

  • CPU and other related hardware helps manage the cache memory.

  • This is small in size.

  • It is used to store the most recently used data.

Virtual Memory

  • It increases the capacity of the main memory.

  • It is a method that involves the hard disk.
