SSC CGL 2023 PYQ — Question 146

The correct answer is Option 3 i.e. Memory Address Register.

In computer systems, MAR refers to the Memory Address Register. This register is a key component of the CPU, responsible for holding the address of the memory location where data needs to be read from or written to. When the CPU needs to access memory, it places the address into the MAR. The MAR then communicates with the memory to perform the necessary action, either fetching data or writing new information.
