    Study Notes

    The Evolution of Computing

    • The word "computer" initially referred to people who performed calculations manually.
    • Early computers were primarily used for mathematical tables, bomb trajectories, and rocketry calculations.
    • Colossus, the world's first programmable, electronic, digital computer, was developed by British codebreaker Tommy Flowers during World War II to decipher the Lorenz cipher.
    • Colossus used vacuum tubes for logic and counting operations and was programmed using switches and plugs.
    • John Napier invented logarithms, a method using lookup tables to simplify complex calculations.
    • Blaise Pascal invented the first calculator in 1645, a mechanical device capable of addition and subtraction.
    • Gottfried Wilhelm von Leibnitz invented the Stepped Reckoner in 1674, an improved calculator that could perform multiplication and division.
    • Joseph-Marie Jacquard adapted punched cards from musical boxes to control looms in 1804, laying the groundwork for data input and output in computers.
    • Charles Babbage designed the Difference Engine and Analytical Engine in the early 19th century, which served as blueprints for modern computers.
    • Lady Ada Lovelace, a mathematician and daughter of Lord Byron, documented Babbage's work and wrote programs for his machines, becoming the first computer programmer.
    • During World War II, codebreakers at Bletchley Park used computational models to decipher enemy messages.
    • Tommy Flowers invented Colossus, the first electronic, digital, programmable computer, which was used at Bletchley Park.
    • Alan Turing published a paper proving that a binary machine could solve any problem based on programmed instructions.
    • John Vincent Atanasoff invented the ABC computer, which used binary digits (1s and 0s) for data processing.
    • Howard Aiken, supported by IBM, built the ASCC computer in 1944, a mechanical relay-based machine that weighed 35 tons.
    • Dr. Grace Murray Hopper worked with Aiken and contributed to the development of the COBOL programming language, the first to use English-like syntax.
    • Hopper coined the term "debugging" after a moth flew into a computer and caused an error.
    • Jack Kilby invented the first integrated circuit in 1959, leading to smaller and more reliable computers.
    • The microelectronics revolution resulted in mass-produced integrated circuits, replacing complex hand-wired circuits.
    • Bill Gates founded Microsoft and developed software for the emerging personal computer market.
    • Steve Jobs co-founded Apple and introduced the Graphical User Interface (GUI), revolutionizing computer usability.
    • The iPod launched in 2001, transforming the music player market with its digital portability.
    • Microsoft and Apple engaged in legal battles over GUI technology and market dominance.

    Bletchley Park

    • Colossus, a secret computer developed at Bletchley Park, was crucial for breaking the Lorenz cipher during World War II.

    Artificial Intelligence

    • The Mechanical Turk, a chess-playing machine from 1770, is considered one of the earliest examples of artificial intelligence.
