NIMCET 2020 — Computer PYQ

NIMCET | Computer | 2020

The memory unit which directly communicates with the CPU is known as

Choose the correct answer:

Explanation

Solution

Step 1: Identifying the Communication Path The Primary Memory (also called Main Memory or RAM) is the central storage unit in a computer system that communicates directly with the CPU. It holds the data and instructions that the CPU is currently processing.

Step 2: Analysis of Options

Primary Memory / Main Memory: These terms are used interchangeably. This memory is volatile and provides the high-speed access required by the CPU.
Secondary Memory: Includes devices like Hard Drives. The CPU cannot access these directly; data must be moved to Primary Memory first.
Auxiliary Memory: Another term for Secondary Memory.
Register: These are small, extremely fast storage locations inside the CPU itself, used for immediate data manipulation, rather than being classified as the "Memory Unit" the CPU fetches from.

Final Answer: The memory unit which directly communicates with the CPU is Primary Memory.
