The correct answer is option 4: Memory Buffer Register

Key Points

  • MBR stands for Memory Buffer Register in Computer Architecture.
  • It is used to temporarily store data being transferred to and from the memory.
  • Also known as **Memory Data Register (MDR)** in some texts.
  • MBR holds the contents of memory read or data to be written to memory.

Additional Information

  • MBR works closely with MAR (Memory Address Register) during memory operations.
  • MAR holds the address, while MBR holds the data.
  • Options 1, 2, and 3 are not standard terms in computer architecture.

Hence, the correct answer is: option 4: Memory Buffer Register
