Computer Classification Types

Classification of Computers by Type

• Computers can be classified based on their size, type, generation, and purpose.
• There are three main types of computers based on their operation: digital, analog, and hybrid computers.

Digital Computers

• Process countable objects.
• Examples: mainframe computers, minicomputers, microcomputers, and calculators.

Analog Computers

• Process uncountable objects.
• Use substances such as liquids or springs to measure values.
• Examples: thermometer, stethoscope, speedometer, liquid dispenser meter, and electricity meter.

Key Concepts
