  • Slide Rule

    Slide Rule
    Mechanical analog device invented by William Oughtred. Used for mathematical calculations before calculators were invented.
  • Charles Babbage

    An English mathematician credited with creating the first automatic digital computer.
  • Ada Lovelace

    Ada Lovelace
    Wrote the first algorithm for Charles Babbage's Analytical Engine, making her the first computer programmer.
  • Alan Turing

    Introduced the "Turing Machine", a model for how computers could process data. He was known as the father of modern computing.
  • ENIAC

    ENIAC
    ENIAC, or Electronic Numerical Integrator and Computer, is a general purpose electronic digital computer.
  • Harvard Mark I

    Harvard Mark I
    Developed by Howard Aiken, in collaboration with IBM. It was his first fully functional computer.
  • Transistors

    Used to amplify or switch electrical signals. Replaced inefficient vacuum tubes. Used in machines like the ENIAC.
  • Grace Hopper

    Grace Hopper
    Hopper was involved in the creation of UNIVAC, the first all-electronic digital computer. She also invented the first computer compiler, a program that translates written instructions into codes.
  • IBM 701

    IBM 701
    IBM's first computer, the 701, was introduced. It was designed for scientific work and research.
  • Steve Wozniak

    Steve Wozniak designed the Apple I as his personal computer. It was well received and Wozniak and Steve Jobs decided to manufacture it.
  • Apple I

    Apple I
    Apple I, one of the very first microcomputers, manufactured and released for sale to general public. Sold for $666.66
  • Apple II

    Apple II released. Owners had the option to trade their Apple I for an Apple II.
  • GUI and Xerox Star

    GUI innovation occurs at the Xerox Corporation’s Palo Alto (California) Research Center (PARC). A computer workstation called Xerox Star uses a technique called “bit mapping” in which everything on the computer screen is a picture. Bit mapping welcomed the use of graphics and allowed the computer screen to display exactly what would be output from a printer.
  • World Wide Web

    The development of the World Wide Web begins by Tim Berners-Lee and his colleagues.
  • Smartphone prototype

    A prototype of the first smartphone named “Angler” was invented by Frank James Canova.
  • Web Browser Released

    Text-based web browser released to public. Web gives users access to mass media and content—via the deep web, the dark web, and the commonly accessible surface web.
  • First Smartphone

    First Smartphone
    The final version named “Simon Personal Communicator” was developed by IBM and released to the market by BellSouth in 1994.
  • Google

    Google
    Larry Page and Sergey Brin worked from their dorm rooms at Stanford where they built a search engine that used links to determine the importance of individual pages on the World Wide Web. They called this search engine Backrub. Thankfully, they renamed it Google!
  • iPhone

    iPhone
    First iPhone invented by Apple CEO Steve Jobs. It was a touchscreen mobile phone with an iPod, camera and Web-browsing capabilities.
  • Alexa

    Alexa debuts in Amazon's Echo. Virtual assistant compatible with smart devices. Alexa has more than 130,000 skills to assist with!
  • Chat GPT

    AI Chatbots are artificial intelligence programs that generates dialogue. Chat GPT was created by Open AI. It uses machine learning algorithms to process and analyze large amounts of data to generate responses to user inquiries. It is able to understand human language as it is spoken and written. You can type in a question, and it will easily give you an understandable answer.
  • Autonomous Vehicles

    Autonomous Vehicles
    Tesla, currently is a Level 3 automation, with plans for further development. Automation at stage 3 enables a vehicle to operate autonomously, but a human driver must actively monitor conditions and immediately take control of the vehicle when the system alerts them.
