Which is not part of Processing Unit?

  • A. Arithmetic Unit
  • B. Arithmetic Unit
  • C. Arithmetic Unit
  • D. Arithmetic Unit

Answer: Option D

Explanation:

A Hard Disk Drive (HDD) is not part of the Processing Unit (CPU). The CPU consists of the Control Unit (CU), Arithmetic Logic Unit (ALU), and Registers, while an HDD is a separate storage device. Other components like a graphic card or a mouse are also not part of the CPU, but rather separate hardware. 
CPU Components
  • Control Unit (CU): Directs the operations of the processor by interpreting instructions and coordinating tasks.
  • Arithmetic Logic Unit (ALU): Performs mathematical and logical operations.
  • Registers: Small, high-speed storage locations within the CPU used to temporarily hold data and instructions. 
Components not in the CPU
  • Hard Disk Drive (HDD): A long-term storage device for files, programs, and the operating system. 
  • Graphic Card: A separate component designed specifically for rendering images and videos. 
  • Mouse: An input device used for navigation and clicking.
