Question

Which component of the CPU coordinates all activities inside it?

• A. ALU
• B. Control Unit
• C. Register File
• D. Cache

Hint:

Think of the CPU as a factory. The ALU is the workshop where the work gets done, the registers are the workbenches holding tools and parts, and the Control Unit is the factory manager, telling everyone what to do and when.

Answer 1

The Correct Option is B

The Central Processing Unit (CPU) has several main components, each with a specific function.
(A) ALU (Arithmetic Logic Unit): Performs all arithmetic operations (like addition, subtraction) and logical operations (like AND, OR, NOT).
(B) Control Unit (CU): This is the director of the CPU. It fetches instructions from memory, decodes them, and generates control signals to coordinate the activities of all other components of the CPU (like the ALU and registers) and other parts of the computer system.
(C) Register File: A set of high-speed storage locations within the CPU used to hold data and instructions temporarily.
(D) Cache: A small, fast memory that stores frequently used data to speed up access.
The component responsible for coordination and control is the Control Unit.
