Question

Which of the following are the two components of the CPU of a computer?

A.

Control Unit and Bus

B.

Control unit and ALU

C.

ALU and Bus

D.

Registers and Main Memory

Correct option is B

The correct answer is Control unit and ALU.

  • The CPU (Central Processing Unit) is often referred to as the brain of the computer.
  • The two main components of the CPU are the Control Unit (CU) and the Arithmetic Logic Unit (ALU).
  • The Control Unit directs the operation of the processor. It tells the computer's memory, arithmetic/logic unit, and input and output devices how to respond to the instructions that have been sent to the processor.
  • The Arithmetic Logic Unit (ALU) is responsible for performing all arithmetic and logic operations, such as addition, subtraction, multiplication, division, and logical operations like AND, OR, and NOT.

Information Booster:

  • (Control Unit and Bus): The Bus is not a part of the CPU; it is a communication system that transfers data between components of the computer.
  • (ALU and Bus): While the ALU is part of the CPU, the Bus is not.
  • (Registers and Main Memory): Registers are part of the CPU, but Main Memory (RAM) is external to the CPU and part of the computer's overall architecture.
