Which of the following performs the arithmetic and logical operations in a CPU?

Correct option is A

The Arithmetic Logic Unit (ALU) is the part of the CPU responsible for performing arithmetic (addition, subtraction, multiplication, division) and logical (AND, OR, NOT, XOR) operations. It is a crucial component of the processor that handles all mathematical calculations and logical decision-making tasks during program execution.
Important Key Points:
1. The ALU performs all arithmetic calculations such as addition and subtraction, as well as logical comparisons.
2. It works closely with the control unit and memory to process data and execute instructions.
Knowledge Booster:
· Control Unit: Directs the operations of the CPU, but does not perform arithmetic or logical operations.
· Memory Unit: Stores data and instructions temporarily, but does not perform calculations.
· Cache: A small, high-speed memory that stores frequently accessed data but does not execute arithmetic or logic operations.
· Register: Temporarily holds data and instructions for the CPU, but the actual operations are performed by the ALU.
