Describe the main components of a CPU and their functions.

Here are the components and their functions from the CPU diagram:

Components of the Central Processing Unit (CPU) and their functions:

• Control Unit (CU):

  • Function: Directs and coordinates most of the operations in the computer. It fetches instructions from memory, decodes them, and then executes them by sending control signals to other components of the CPU and other devices. It manages the flow of data between the CPU, memory, and input/output devices.

• Arithmetic Logic Unit (ALU):

  • Function: Performs all arithmetic operations (like addition, subtraction, multiplication, division) and logical operations (like comparisons, AND, OR, NOT). It is the part of the CPU that actually executes instructions involving calculations and data manipulation.
