1. Types of computers

1.Supercomputers

  • Definition: The fastest and most powerful computers designed to perform complex calculations at extremely high speeds.

  • Use: Weather forecasting, nuclear research, scientific simulations, and space exploration.

  • Example: IBM Summit, Fugaku (Japan).

2. Mainframe Computers

  • Definition: Very large computers used by big organizations to handle and process massive amounts of data.

  • Use: Banking, insurance, government departments, airlines (for booking and transaction processing).

  • Example: IBM Z-series mainframes.


3. Minicomputers (Mid-range computers)

  • Definition: Smaller than mainframes but larger than personal computers. They can serve multiple users at once.

  • Use: Small organizations, laboratories, and departments for shared data processing.

  • Example: DEC PDP series.


4. Microcomputers (Personal Computers)

  • Definition: The most common type of computer designed for individual use.

  • Use: Education, business, entertainment, and home tasks.

  • Examples: Desktops, laptops, and tablets.


5. Embedded Systems

  • Definition: Special-purpose computers built into other devices to control specific functions.

  • Use: Found in washing machines, cars, ATMs, televisions, and mobile phones.

  • Example: Microcontroller inside a microwave oven.
