Question

Which of the following is not a part of the CPU of a computer?
1. Arithmetic Logic Unit
2. Control Unit
3. Main Memory
4. Mouse

Answer 1

Correct Answer - Option 4 : Mouse

The correct answer is Mouse.

• The mouse is not a part of the CPU of a computer.

 

• CENTRAL PROCESSING UNIT (CPU)
  • It is called the brain of the computer.
  • The CPU can be divided into three main components: (a) ALU (b) CU and (c) Registers.
    • The Arithmetic and Logic Unit (ALU): ALU performs all the mathematical and logical operations on the information supplied to the CPU.
    • Control Unit (CU): It fetches instructions (Programs) from the memory and according to the instructions, controls the flow of data between the ALU and other parts of the computer.
    • Registers: Registers are storage locations that hold instructions or data while the CPU is using them.
• Hence, a mouse is not a part of the CPU of a computer.
