  • Charles Babbage invents the Difference Engine

    Charles Babbage invents the Difference Engine
    The Difference Engine was a echanical computer designed to calculate the times tables. It was a successor to men with pencils and paper because they made mistakes.
  • Ada Lovelace programs a nonexistent computer

    Ada Lovelace programs a nonexistent computer
    Ada Lovelace programmed for a nonexistent computer called the Analytical Engine, invented by Charles Babbage. The Analytical engine used memory, branching, loops, and an arithmetic logic unit, a circuit used for arithmetic and bitwise logical operations. This was the successor to the Difference Engine.
  • Boolean Invented

    Boolean Invented
    In 1854, Gorge Boole invented Boolean Algebra. Booleans rely on statements, and they rely on mathematica and logic. Then they decide whether the statement is true or false, normally represented as a 1 or 0.
  • Samuel Butler suggests that robots may become conscious

    Samuel Butler suggests that robots may become conscious
    In 1863, Samuel Butler suggests that robots may become conscious and overtake humans. This worked perpendicular to the Darwinian Evolution theory; one of biological evolution - organisms will develop through natural variations that will help to 'compete, survive, and reproduce'.
  • Herman Hollerith invents the Tabulating Machine

    Herman Hollerith invents the Tabulating Machine
    The Tabulating Machine was a partly electrical and machanical machine that was used formmarising informantion and accounting.
  • Leonardo Torres y Quevedo makes a smart chess player

    Leonardo Torres y Quevedo makes a smart chess player
    In 1915, Leonardo Torres y Quevedo built a smart chess player: El Ajedrecista.
  • Konrad Zuse invents the first programmable computer

    Konrad Zuse invents the first programmable computer
    From 1936 and on, Konrad Zuse invented Z1, Z2, Z3, and Z4 computers. They were the first mechanical computers using the Binary computer language from punched holes.
  • Alan Turing invents the Bombe

    Alan Turing invents the Bombe
    The Bombe was a mechanical computer, to break German Enigma war codes, filled with mostly cogs and motors, that used contradiction, where the computer would keep looking for patterns and try to find matches (for example – AAA, AAB, AAC, and so on). With good luck, this machine could crack a code in less than 15 minutes.

  • Thomas Watson: "I think there is a world market for about five computers."

    Thomas Watson: "I think there is a world market for about five computers."
    Thomas Watson, CEO of IBM predicted that the world will eventually need 5 computers.
  • Tommy Flowers invents Colossus

    Tommy Flowers invents Colossus
    Colossus was a computer designed to break codes using Boolean, yes or no questions, and counting operations. It was known as the 'first programmable, electronic, and digital' computer in the world.
  • Grace Hopper programs the Harvard Mark I

    Grace Hopper programs the Harvard Mark I
    She was one of the first programmers of the Harvard Mark I computer in Harvard, and she invented the first compiler. (A complier is a program, or a set of programmes, used to translate one programming language to another.)

  • The term 'Bug' appears

    The term 'Bug' appears
    In 1946, Grace Hopper was working on the Mark 2 and 3. When the Mark 2 suddenly stopped working, Grace stayed up all night looking for the problem. Finally, she found a moth in the system. She took it out, put it on the table, and wrote 'Bug in computer'. Thus the term Bug.
  • William Shockley invents the transistor

    William Shockley invents the transistor
    In 1947, William Shockley and 2 others invented the transistor. A transistor is a tiny switch that can be turned on or off by electric signals. The invention of the transistor lead to Booleans; yes or no decisions.
  • Alan Turing devises the Turing Test

    Alan Turing devises the Turing Test
    The Turing Test is a test to tell the difference between a computer and a human’s interaction and/or conversation. If the ‘evaluator’ cannot tell the difference at least of 70% of the conversation in 5 minutes, then the machine is said to have passed the test.

  • MIT AI Lab.

    MIT AI Lab.
    John McCarthy and Marvin Minsky found the MIT AI Lab, Recently, the lab has joined with Toyota on a $25 million US dollar research centre for self driving cars.
  • Douglas Engelbart invents the mouse and works on founding the field of HCI

    In the early 1960s, Douglas Engelbart invented the mouse. It didn’t use a laser, but instead it was mostly mechanical. He then worked on Human-Computer Interaction. His law ‘Engelbart's Law’ is the observation that the intrinsic rate of human performance is exponential, which basically means that the natural growth rate of human performance will keep rapidly increasing.
  • ELIZA

    ELIZA
    Joseph Weizenbaum builds ELIZA. It was a program that talk to you about anything. It has a speciality in physiotherapy.
  • Intel introduces first commercial Microprocessor (called 4004)

    Intel introduces first commercial Microprocessor (called 4004)
    A Microprocessor is a computer processor that intigrates the whole CPU (Central Processing Unit) of a computer into a single tiny chip. It is a programmable object that reads binary (a computer lanuage based on 1s and 0s). Teensy transistors are put on a teensy circuit board. There is a physical boundary, though, as to how many transistors and other stuff you can actually fit onto a Microprocessor.
  • Xerox PARC invents stuff

    Xerox PARC invents stuff
    The process of laser printing with a bitmapped (or broken down) electronic image on a xerographic copier drum (a dry photocopying method, without wet chemicals) is developed.
    Xerox PARC also invented the rolling-ball mouse.

  • Bill Gates and Paul Allen invent the Traf-O-Data

    Bill Gates and Paul Allen invent the Traf-O-Data
    When Bill Gates was a teen, his friend Paul Allen and he invented the Traf-O-Data, which was a traffic measurement system.

  • Vint Cerf and Robert E. Kahn invent the Internet

    In 1973, Vint Cerf and Robert Kahn invented a connection between computers.
    Two computers were set up and one computer typed the letter ‘L’. By phone they asked the other side, “did you see the L?” The answer was yes. This was tried again with the letter ‘O’. It worked again. Unfortunately, when the letter ‘G’ was typed, the system crashed, but it was a breakthrough.
    This is what resulted as what we know as the Internet.

    Xerox PARC invents the GUI we know today
    Xerox PARC invents cut-and-paste, icons, pop-up menus, and overlapping menus.
  • Bill Gates and Paul Allen buy DOS

    Bill Gates and Paul Allen buy DOS
    In 1981, Microsoft bought the DOS (Disk Operating System), and used it to improve – (not invent) – interactive OS. They soon changed the name to MS-DOS (Microsoft DOS).

  • Steve Jobs, Steve Wozniak, and Ronald Wayne establish Apple Inc.

    Steve Jobs, Steve Wozniak, and Ronald Wayne establish Apple Inc.
    Apple Incorporated was first established to sell the Apple I personal computer kit. These computers were actually designed and hand built by Steve Wozniak, and not Steve Jobs. It was sold as a motherboard with CPU and RAM, and not as a fully pre-assembled kit. It was priced at $666.66 then; $2,763 in 2015 US dollars. In 1985, John Sculley (president of Pepsi and CEO of Apple at the time, founder of Misfit Wearables and Obi Mobiles) fired Steve Jobs from his own company. Steve then founded NeXT,
