Which one of the following is NOT a component of the CPU?

Correct option is D

The motherboard is not a component of the CPU. The CPU (Central Processing Unit) consists of components like the Arithmetic Logic Unit (ALU), Control Unit (CU), and Registers, which work together to execute instructions and process data. The motherboard, on the other hand, is a separate hardware component that houses the CPU, memory, and other peripherals.

Important Key Points:

1. Registers: Small, high-speed storage locations inside the CPU used for temporary data storage during processing.
2. Arithmetic Logic Unit (ALU): Performs arithmetic (addition, subtraction) and logical (AND, OR) operations.
3. Control Unit (CU): Directs and coordinates the operations of the CPU, fetching and interpreting instructions.

Knowledge Booster:

• Motherboard: A circuit board that connects and integrates all computer components, including the CPU, RAM, storage devices, and input/output peripherals.
• The CPU is also known as the processor or the brain of the computer, as it handles most computational tasks.
• The CPU's functionality relies on the motherboard, which facilitates communication between the CPU and other components, but the motherboard itself is not part of the CPU.
