    Study Notes

    Generations of Computers

    • Modern computing’s origins trace back to the 16th century
    • Computers improved continuously in terms of speed, accuracy, size, and price over time

    Key Terms

    • Vacuum tube: Used for controlling electron flow in a vacuum.
    • Transistor: Used for controlling electricity flow, functioning as a switch or amplifier.
    • Integrated circuit (IC): Silicon chips containing circuits like transistors and resistors.
    • Microprocessor: Components containing the CPU and its circuits, housed within an IC.
    • Central processing unit (CPU): The brain of the computer, responsible for processing and operations.
    • Magnetic drum: A cylinder for data storage.
    • Magnetic core: Arrays of small rings used for information storage.
    • Machine Language: The language computers accept, expressed in binary digits. It is also known as a low-level programming language.
    • Memory: Used for storing data, information, and programs in a computer.
    • Artificial intelligence: The field of creating intelligent machines and behaviors.

    Computer Generations

    • First Generation (1940-1956): Vacuum tube based, large, and heavy.
      • Examples: ENIAC, EDVAC, UNIVAC
    • Second Generation (1956-1963): Transistor based, reduced size and power consumption.
      • Examples: PDP-8, IBM 1400 series, IBM 7090, and 7094, UNIVAC 1107, CDC 3600
    • Third Generation (1964-1971): Integrated circuit (IC) based, increased speed and reliability.
      • Examples: IBM 360, IBM 370, PDP-11, NCR 395, B6500, UNIVAC 1108
    • Fourth Generation (1971-Present): Microprocessor based, further decreased size, enhanced power, and introduced operating systems.
      • Examples: Desktop computers, laptops, tablets, smartphones
    • Fifth Generation (Present and Beyond): Based on artificial intelligence, uses Ultra Large-Scale Integration (ULSI) technology, and parallel processing. Emphasizes natural language processing.
      • Examples: AI-powered systems, advanced robotics

    Before Computers

    • Mechanical calculators played a crucial role before the modern computer era:
      • Abacus (ca. 2700 BC)
      • Pascal's Calculator (1652)
      • Stepped Reckoner (1694)
      • Arithmometer (1820)
      • Comptometer (1887) and Comptograph (1889)
      • The Difference Engine (1822)
      • Analytical Engine (1834)
      • The Millionaire (1893)
