Charles Babbage
Charles Babbage began to construct a small difference engine in c. 1819[4] and had completed it by 1822 (Difference Engine 0).[5] He announced his invention on 14 June 1822, in a paper to the Royal Astronomical Society, entitled "Note on the application of machinery to the computation of astronomical and mathematical tables".[6] This machine used the decimal number system and was powered by cranking a handle. -
Herman Hollerith, Punch Card
In 1881, Herman Hollerith began designing a machine to tabulate census data more efficiently than by traditional hand methods. The U.S. Census Bureau had taken eight years to complete the 1880 census, and it was feared that the 1890 census would take even longer. Hollerith invented and used a punched card device to help analyze the 1890 U.S. census data. -
HP
The Hewlett-Packard Company, was an American multinational information technology company headquartered in Palo Alto, California. HP developed and provided a wide variety of hardware components, as well as software and related services to consumers, small and medium-sized businesses (SMBs), and fairly large companies, including customers in government, health, and education sectors. The company was founded in a one-car garage in Palo Alto by Bill Hewlett and David Packard in 1939. -
Turning
The Turing test, originally called the imitation game by Alan Turing in 1949,[2] is a test of a machine's ability to exhibit intelligent behaviour equivalent to that of a human. In the test, a human evaluator judges a text transcript of a natural-language conversation between a human and a machine. The evaluator tries to identify the machine, and the machine passes if the evaluator cannot reliably tell them apart. -
Grace Hopper, COBOL
In 1952, Hopper and her team created the first compiler for computer languages. A compiler is a program that translates human-readable source code into computer-executable machine code. “That was the beginning of COBOL, a computer language for data processors [the word is an acronym for COmmon Business-Oriented Language],” she said. “I could say ‘subtract income tax from pay’ instead of trying to write that in octal code or using all kinds of symbols.” -
AI
The field of AI research was founded at a workshop held on the campus of Dartmouth College in 1956.[1] Attendees of the workshop became the leaders of AI research for decades. Many of them predicted that machines as intelligent as humans would exist within a generation. The U.S. government provided millions of dollars with the hope of making this vision come true. -
Apple
Apple Computer, Inc. was founded on April 1, 1976, by college dropouts Steve Jobs and Steve Wozniak, who brought to the new company a vision of changing the way people viewed computers. Jobs and Wozniak wanted to make computers small enough for people to have them in their homes or offices. Simply put, they wanted a computer that was user-friendly. -
WIFI
Wi-Fi technology has its origins in a 1985 ruling by the U.S. Federal Communications Commission that released the bands of the radio spectrum at 900 megahertz (MHz), 2.4 gigahertz (GHz), and 5.8 GHz for unlicensed use by anyone. Technology firms began building wireless networks and devices to take advantage of the newly available radio spectrum, but without a common wireless standard the movement remained fragmented, as devices from different manufacturers were rarely compatible. -
Windows
The first version of Windows, Windows 1.0, was released on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). -
Tim Burners-Lee
Berners-Lee proposed an information management system on 12 March 1989[5][6] and implemented the first successful communication between a Hypertext Transfer Protocol (HTTP) client and server via the Internet in mid-November.[7][8][9][10][11] He devised and implemented the first Web browser and Web server and helped foster the Web's subsequent explosive development. -
Douglas Engelbart, GUI
Douglas Engelbart (born January 30, 1925, Portland, Oregon, U.S.—died July 2, 2013, Atherton, California) was an American inventor whose work beginning in the 1950s led to his patent for the computer mouse, the development of the basic graphical user interface (GUI), and groupware. Engelbart won the 1997 A.M. Turing Award, the highest honour in computer science, for his “inspiring vision of the future of interactive computing and the invention of key technologies to help realize this vision.” -
Iphone
The iPhone is a line of smartphones developed and marketed by Apple that run iOS, the company's own mobile operating system. The first-generation iPhone was announced by then–Apple CEO Steve Jobs on January 9, 2007, at Macworld 2007, and launched later that year. -
Chromebook
The first Chromebooks for sale, by Acer Inc. and Samsung, were announced at the Google I/O conference in May 2011 and began shipping on June 15, 2011.[7] Lenovo, Hewlett-Packard (now HP Inc.) and Google itself entered the market in early 2013. Chromebooks are optimised for web access. They also run Android apps, Linux applications, and Progressive web apps which do not require an Internet connection.[1] They are manufactured and offered by various OEMs. -
Apple Watch
The Apple Watch is a brand of smartwatch products developed and marketed by Apple. It incorporates fitness tracking, health-oriented capabilities, and wireless telecommunication, and integrates with watchOS and other Apple products and services. The Apple Watch was released in April 2015, and quickly became the world's best-selling wearable device.
