    Study Notes

    Classification of Computers

    • Computers can be classified according to size, data handling, and purpose.
    • There are four main classifications by size: supercomputer, mainframe, minicomputer, and microcomputer.
    • The categories can be differentiated by their size, price, memory, speed, and functionality.

    Supercomputer

    • Supercomputers are the largest and most powerful computers, used for complex mathematical calculations.
    • Industries that use supercomputers include:
      • Weather forecasting
      • Climate research
      • Oil exploration
      • Molecular modeling
      • Quantum mechanics
      • Cryptanalysis

    Mainframe

    • Mainframes are used for bulk data processing.
    • Typical tasks performed by mainframes include:
      • Census data processing
      • Transaction processing
    • These computers are sensitive to environmental conditions, requiring trained operators for operation.

    Minicomputer

    • Minicomputers are smaller than mainframe computers with less memory and storage.
    • They can be used by end users directly and are not sensitive to external environments.
    • Minicomputers offer a limited range of software and peripherals, but they are more cost-effective than mainframes and supercomputers.

    Microcomputer

    • Microcomputers are the smallest and most user-friendly computers, commonly used for personal work and entertainment.
    • Characteristics of microcomputers include:
      • Low cost
      • Widely available software
      • Easy to learn
      • Limited peripherals
      • Typically have components:
        • Monitor
        • CPU
        • Keyboard
        • Mouse
        • Speakers
        • Modem
        • Printer
