Question

Which among the following statements is incorrect about Central Processing Unit?

A.

Control Unit controls the order in which instructions enter and leave the processor and how the instructions are executed.

B.

Arithmetic Logic Unit is responsible for taking the input, converting it into a signal, and storing it for further processing.

C.

Arithmetic Logic Unit is also known as the mathematical brain of a computer.

D.

Control Unit directs and manages operation sequences.

Correct option is B

The statement "Arithmetic Logic Unit (ALU) is responsible for taking the input, converting it into a signal, and storing it for further processing" is incorrect. The ALU is responsible for performing arithmetic and logical operations in a computer. It does not handle input conversion or storage, which are functions of input devices or memory components.

Important Key Points:

  1. The Arithmetic Logic Unit (ALU) performs calculations and logical comparisons, earning it the name "mathematical brain" of the computer.
  2. The Control Unit (CU) manages the sequence of operations and controls the flow of data within the CPU.
  3. Storage and signal conversion are not the responsibility of the ALU.

Knowledge Booster:

  • Control Unit: Controls the sequence of instructions and manages data flow within the processor.
  • Arithmetic Logic Unit: Performs arithmetic operations like addition, subtraction, and logical comparisons.
  • Known as the mathematical brain because it handles computation and decision-making processes essential for program execution.
