Which register stores the ADDRESS of the memory location being accessed?
Explanation
The MAR stores the address (location) of memory the CPU needs to access. It is different from MDR which stores the actual data at that address.
Reference: Computer Studies Textbook , Page 4
Hint
MAR holds an address not data — think of it like a house number.
