The Correct Answer is:(C) Control Unit
Explanation :
The Control Unit (CU) is a crucial component of the Central Processing Unit (CPU) that coordinates and directs all operations of a computer.
It ensures that instructions are executed in the correct sequence and manages data flow between different components.
  • Fetches instructions from memory.
  • Decodes and interprets instructions.
  • Directs the Arithmetic Logic Unit (ALU) and registers to perform tasks.
  • Controls input and output devices to ensure smooth data transfer.
  • Regulates the flow of data within the CPU and between system components.
Information Booster:

The CPU consists of three main components:

  1. Control Unit (CU): Manages and coordinates all functions.
  2. Arithmetic Logic Unit (ALU): Performs mathematical and logical operations.
  3. Memory Unit: Stores data and instructions temporarily for quick access.
Additional Knowledge:
  • Motherboard: The main circuit board that connects and holds all essential computer components, including the CPU, RAM, and storage. 
  • Keyboard: An input device used to enter data into the computer.
  • Mouse: Another input device that allows users to interact with the computer by pointing and clicking .
