Correct Answer: Correct answer is: (B) Memory data register.

Exam Relevance: Computer Architecture, Digital Systems, Microprocessors

Difficulty: Easy

Concept notes: The memory data register (MDR) is a register that holds the data to be written into or read out of a memory location.

Common Mistakes: Students may confuse the memory data register with the memory address register, which holds the address of the memory location to be accessed.

Explanations: The memory data register (MDR) is used to store the actual data that is being read from or written to memory. When a read operation is performed, the data from the addressed memory location is transferred to the MDR. Conversely, during a write operation, the data in the MDR is transferred to the addressed memory location. This makes the MDR the correct answer as it directly contains the data being manipulated.

Option Analysis:

Option A: The memory address register (MAR) holds the address of the memory location to be accessed, not the data itself.
Option B: The memory data register (MDR) holds the data to be written into or read out of the addressed location, making it the correct answer.
Option C: The program counter (PC) holds the address of the next instruction to be executed, not the data being read or written.
Option D: The index register is used to modify addresses, not to hold the data being read or written.

Mnemonic: MDR holds the data, not the address.
