    Study Notes

    First Generation of Computers

    • Early computers were large and used vacuum tubes
    • The Atanasoff-Berry Computer (ABC), Colossus, Electronic Numerical Integrator and Computer (ENIAC), Universal Automatic Computer I (UNIVAC I), Whirlwind, and the IBM 701 were first-generation computers
    • Vacuum tubes were three-terminal devices consisting of a cathode, grid, and plate
    • First-generation computers used vacuum tubes

    Second Generation of Computers

    • The use of transistors replaced vacuum tubes in the second generation of computers
    • Transistors were smaller, cheaper, and more reliable
    • Experiments done by the University of Manchester, resulted in the creation of one of the earliest transistor computers
    • The first prototype machine was built in 1953 and the full-size version was commissioned in 1955
    • The transistor is a three-terminal, solid-state electronic device that can control electric current or voltage

    Third Generation of Computers

    • The third generation of computers came as a result of the use of semiconductors
    • Key improvements included speed and efficiency
    • Users could interact with third-generation computers using keyboards and monitors
    • Operating systems made it possible for computers to handle various applications simultaneously
    • Computers became smaller and cheaper, making them available to a wider audience

    Fourth Generation of Computers

    • The rise of microprocessors led to the fourth generation of computers
    • This generation saw thousands of integrated circuits being placed on single silicon chips
    • The Intel P4004, released in 1969, was the world's first microprocessor

    Computer Systems

    • Computer systems are made of various components each with its own function
    • The input unit receives user commands in the form of data and converts them into digital language format, sending it to the processing unit
    • The processing unit processes the information it receives from the input unit
    • The memory unit is responsible for storing data from input devices and the results from output devices
    • The control unit manages the computer device functions and serves as the central component of the CPU, transferring commands to the ALU
    • The arithmetic-logic unit is tasked with carrying out mathematical calculations and comparisons, as well as making decisions
    • The output unit displays the process resulting from the input and processing units
    • The output unit uses various devices including monitors

    Operating Systems

    • Operating systems (OS) control computer hardware and enable users to utilize the power of the system
    • Operating systems are a collection of software programs and commands
    • Key features of operating systems include abstraction, volatility, executable programs, expensive software, user-friendliness, and unpredictability

    Common Operating Systems

    • Windows, Mac OS, Android, and iOS are the most common operating systems in use today

    Internet and the Web

    • The web is interconnected and designed to allow easy access to various resources
    • The web is accessible through hypertext or hypermedia links, which allow users to move smoothly from one page to another
    • Tim Berners-Lee invented the World Wide Web (WWW) in 1989
    • The first web page was launched on August 6, 1991
    • The expansion of the web went global by the end of 1991
    • The Internet is a vast network connecting millions of computers globally
    • The Internet includes copper telephone wires, TV cables, and fiber optic cables
    • The Internet allows for the seamless connection of computers across the globe

    The Process of an Internet Connection

    • When you enter a website the computer sends a request to the server where the website is stored
    • Once the server receives the request, it retrieves the website and sends the data back to the computer.
