Computer hardware refers to the physical components that constitute a computer system. It encompasses tangible elements that are visible and can be touched. The following is an overview of various hardware components:

 

Examples of hardware components:

  1. Monitor
  2. Motherboard
  3. CPU (Central Processing Unit)
  4. RAM (Random Access Memory)
  5. Expansion Cards
  6. Power Supply
  7. Optical Disk Drive
  8. Hard Disk Drive
  9. Keyboard
  10. Mouse, etc.

Computer hardware is broadly categorized into two main divisions:

 

  1. System Unit:

The system unit houses essential components critical to a computer’s functioning. This includes the central processing unit (CPU), responsible for major processing tasks. The system unit comprises the motherboard, which holds the microprocessor chip, memory chips, expansion slots and cards, buses, and ports.

  1. Peripheral:

Peripherals are additional devices connected to a computer to enhance its functionality. These devices serve specific purposes and cannot operate independently. Examples include webcams, printers, and mice. Peripheral devices are further categorized into input and output devices:

 

Input Peripheral Devices:

  1. Keyboard
  2. Pointing devices (e.g., Mouse)
  3. Gaming Devices (e.g., Joystick, Gamepad)
  4. Audio Input Devices (e.g., Microphones)

 

Output Peripheral Devices:

  1. Printer
  2. Speaker
  3. Headphones
  4. Monitor

 

Computer Software:

Software refers to programs processed by hardware to solve problems or perform tasks. There are two main categories of software:

 

  1. System Software:

System software is designed to operate a computer’s hardware and application programs. It acts as an interface between hardware and user applications, including components like BIOS (Basic Input Output System), the BOOT program, and Assembler.

 

  1. Application Software:

Application software consists of instructions written by vendors to perform specific tasks. Examples include MS Word, Skype, and Explorer. These programs enable users to carry out various functions on the computer.
