Study Notes

Central Processing Unit (CPU) Elements

  • The three elements associated with the CPU are the Arithmetic Logic Unit (ALU), Control Unit (CU), and Registers.
  • The ALU performs all arithmetic and logical operations.
  • The Control Unit directs operations of the processor and coordinates instructions from memory.
  • Registers provide a small amount of high-speed storage for immediate data and instructions.

Hardware Component for Computation

  • The Arithmetic Logic Unit (ALU) is responsible for actual computation and logical operations in a computer.
  • It handles addition, subtraction, multiplication, division, and logical operations such as comparisons.

Components of Hardware

  • Hardware components include input devices (like keyboards and mice), output devices (like monitors and printers), storage devices (like hard drives and SSDs), and the motherboard.
  • It also encompasses the CPU, RAM, and various peripherals that facilitate computing tasks.

Role of Main Memory

  • Main memory, typically RAM, temporarily stores data and instructions that the CPU accesses during operation.
  • It provides fast read and write access to support active applications and processes in real time.

Functions of Input and Output Devices

  • Input devices allow users to enter data and commands into the computer, such as keyboards, mice, and scanners.
  • Output devices convey results from the computer to the user, including monitors, printers, and speakers.
  • Together, they facilitate interaction between the user and the computer system.
