    Study Notes

    Inventions in Mechanical Calculation

    • Gottfried Leibniz invented the first mechanical calculator capable of multiplication in 1674.
    • Joseph-Marie Jacquard developed the Jacquard Loom in 1804, an automatic weaving machine controlled by punched cards.
    • Charles Babbage designed the Difference Engine (1822) and the Analytical Engine (1834), pioneering designs for mechanical computers, although he never built a functioning model.
    • Herman Hollerith created a tabulating machine in 1890 for the U.S. Census, using punched cards for data input, laying the groundwork for IBM.
    • Konrad Zuse's Z1 (1938) was a programmable electronic calculator, leading to the Z3 (1941), the first with automatic operation.
    • IBM partnered with Harvard University to create the Mark I (1943), a large electronic calculator using electromechanical relays.

    Generations of Computer Development

    First Generation (1946-1959)

    • ENIAC, the first electronic computer, was designed by J. Presper Eckert and John W. Mauchly in 1946, occupying 167 square meters and weighing 27 tons with vacuum tubes.
    • UNIVAC I, also designed by Eckert and Mauchly, was the first commercial computer.
    • EDVAC, designed by Von Neumann in 1952, was the first stored program computer.

    Second Generation (1959-1965)

    • Second-generation computers utilized transistors, making them smaller, faster, and more reliable than their vacuum tube predecessors.
    • Key programming languages COBOL and FORTRAN emerged during this era, with COBOL preferred in business and FORTRAN in scientific applications.
    • IBM's transistorized 1401 mainframe computer expanded mainframe usage across businesses.
    • The American Standard Code for Information Interchange (ASCII) was introduced in 1963, establishing a critical character set standard for computers.
    • IBM's System/360 revolutionized computing with its integration of various systems.

    Uses of ICT in Daily Life

    Education

    • ICT enhances interactivity in teaching, facilitating presentations, and simulations for efficient learning.

    • Online testing and software evaluation enable instant feedback for students.
    • Research is simplified through search engines and access to global libraries and experts via digital communication.

    Banking

    • Computers serve as the core of modern banking systems, enabling electronic banking services and real-time transactions.
    • Bank administrators use automated systems to manage activities and facilitate inter-branch transactions.

    Industry

    • Computers assist in production planning, control systems, and product design, increasing efficiency and safety using robotics.
    • Data collection and analysis for research are conducted through computer systems.

    Business

    • Business professionals can monitor accounts, transactions, and cash flow through computer systems, improving operational oversight.

    Internet

    • Widespread access to the internet enhances communication, information sharing, and online community creation, alongside risks like identity theft.
    • ICT tools, such as blogs and video-sharing platforms, allow for global content sharing and collaboration.
    • Remote collaboration has become feasible across businesses, science, and engineering sectors, reducing costs and improving outcomes.

    Social and Economic Impact of ICT

    • ICT fosters balanced regional economic growth by creating employment opportunities in smaller cities.
    • It enhances corporate governance practices through global exposure and advanced information technology applications.
