JAMIA 2026 — Computer PYQ

Correct Answer: (d) Register

Detailed Explanation

As seen in image_8db33a.png, the question asks to identify the memory type that is structurally an integral part of the Central Processing Unit ($\text{CPU}$).

• Registers: These are small, high-speed storage locations located directly inside the internal architecture of the $\text{CPU}$. They are used by the processor to hold data temporarily during instruction execution, such as operands, memory addresses, and intermediate results.

• Speed and Proximity: In the memory hierarchy, registers sit at the absolute top layer. This means their access time is minimal, matching the clock speed of the processor itself:

  \text{Access Time}_{\text{Register}} < \text{Access Time}_{\text{Cache}} < \text{Access Time}_{\text{RAM}}
