    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.
