Solution:
  • Register memory is the smallest and fastest memory in a computer.
  • It is not a part of the main memory and is located in the CPU in the form of registers, which are the smallest data holding elements.
  • A register temporarily holds frequently used data, instructions, and memory address that are to be used by CPU.
  • They hold instructions that are currently processed by the CPU. All data is required to pass through registers before it can be processed.
  • So, they are used by CPU to process the data entered by the users.
