Explanation of the Topic

  1. Analogue Computers:
    • Definition: Analogue computers measure continuous data. They use physical quantities to represent information.
    • Examples: Thermometers, Speedometers.
    • Function: They are used in applications where data is continuously changing.
  2. Digital Computers:
    • Definition: Digital computers use binary numbers (0 and 1) to process data. They handle discrete data.
    • Examples: Personal Computers, Laptops, Smartphones.
    • Function: They are used in applications that require precise data processing and calculations.
  3. Hybrid Computers:
    • Definition: Hybrid computers combine features of both analogue and digital computers. They can process both continuous and discrete data.
    • Examples: Medical Equipment, Automated Systems.
    • Function: They are used in specialized applications that need both types of data processing.
