Answer:
Option B is correct.
CPU is used to fetch, decode and execute instructions. The CPU component used to perform this specific task is the Control Unit.
Explanation:
- The arithmetic-logic unit (ALU) is the part of a computer processor (CPU) that carries out arithmetic and logic operations on the operands in computer instruction words.
It doesn't do floating point computations (That's for the Floating Point Unit (FPU)). This makes option A false.
- Principal components of a CPU include the arithmetic logic unit (ALU) that performs arithmetic and logic operations, processor registers that supply operands to the ALU and store the results of ALU operations, and a control unit that ***orchestrates the fetching (from memory) and execution of instructions*** by directing the coordinated operations of the ALU, registers and other components.
- Control Unit is a component of a computer's central processing unit (CPU) that directs the operation of the processor. It tells the computer's memory, arithmetic and logic unit and input and output devices how to respond to the instructions that have been sent to the processor.
It is not directly and expressly used to perform integer arithmetic and bitwise logic operations.
