Describe the functions of the Control Unit and ALU within a CPU.

Here are the functions for each component of the CPU:

• 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. It manages the flow of data and instructions within the CPU and to other parts of the computer system.

• 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 and performs calculations.
