Content
Explanation of the Topic
- 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.
- 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.
- 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.
