Identify the three elements of a CPU and describe the role of each.

Program Plan Intro

Components of computer:

Computer has four major components as follows:

  • Central processing unit (CPU):
    • CPU plays the key role in a computer by carrying out instructions of a computer program.
    • It is basically known as the brain of the computer.
    • It performs all the basic logic, arithmetic, controlling, and input/output operations that are specified by the instructions.
  • Memory unit:
    • Once computer program instructions set are transformed into machine code by CPU, then the machine code is stored in memory.
    • Then the CPU fetches the required data and instructions from memory, perform the required operations and then sends the result and next set of instructions back to the memory.
  • Input devices:
    • Input devices are used by the user to feed information to computer, such as a hard drive, keyboard, or a networking card.
    • These devices get the data from outside world into computer in the way that human eyes and ears bring the data to brain.
  • Output devices:
    • Output devices are used by computer to deliver the information to the user, such as a monitor, printer, and speaker.
    • The CPU takes the machine code present in memory and converts it into a format that is required by monitor’s hardware.
    • Then the monitor’s hardware alters that information into different light intensities such as words or pictures are seen.

Explanation of Solution

Elements of CPU:

The main three key elements of a CPU are as follows:

  • Arithmetic/Logic Unit (ALU)
  • Control Unit (CU)
  • Memory

Role of each element of CPU:

Arithmetic/Logic Unit (ALU):

  • It helps in performing the arithmetic and logical operations within the CPU.
  • All the calculations are performed by this unit of CPU.

Control Unit (CR):

  • It interprets the instruction execution.
  • It fetches the instruction from the main memory and tells the user which instruction to execute, and other parts of system such as ALU and memory unit perform the operations.
  • Control unit consists of two things as follows:
    • Program counter:
      • It specifies which instruction to be executed...
