  • Mouse
  • Scanner

2. Processing

CPU processes the data and converts it into meaningful information.

3. Output

Results are displayed through:

  • Monitor
  • Printer
  • Speakers

4. Storage

Data is saved in:

  • Hard disk

Used to store data permanently:

  • HDD (Hard Disk Drive)
  • SSD (Solid State Drive)

SSD is faster than HDD.

4. Motherboard

It is the main circuit board that connects all components.

5. Input Devices

Used to enter data:

  • Keyboard
  • Mouse
  • Microphone

6. Output Devices

Used to display results:

  • Monitor
  • Printer
  • Speakers

Software Components of Computer

Software is a set of instructions that runs the hardware.

1. System Software

Examples:

  • Windows
  • Linux
  • macOS

It controls the computer system.

2. Application Software

Examples:

  • MS Word
  • Chrome browser
  • Photoshop

Used by users for specific tasks.
