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.
