1947-1951: UNIVAC I, Universal Automatic Computer I, by Presper Eckert with John Mauchly (Sperry Rand), in collaboration with John Von Neumann, marketed by the Univac Division of Remington Rand. 1948-1951: EDVAC, Electronic Discrete Variable Automatic Computer, electronic digital computer using numbering base of two, perforated cards and vacuum tubes, by Presper Eckert with John Mauchly and in collaboration with John Von Neumann. The three scientists were awarded the Nobel Prize in 1956. 1951: LEO, electronic digital computer using numbering base of two, serially built and commercially marketed. Claude Shannon greatly influenced further development of computers using numbering base of two, and definitely provoked the demise of the numbering base of ten for nearly all advanced computers. The computers interchanged meaningless data while about twenty people watched the historical event, which MARKS THE START OF INTERNET. The Internet is not a centralised network as most of the networks listed above, the Internet is a re-routable network, and this is a key point for not considering those networks a part of 'Internet' as the term is commonly used, what is billiards although strictly speaking they may also use an Internet Protocol. This was hardly possible in 1952, when contact point transresistors or junction transistors were the only kinds of transistor available.

Made possible by the flat transistor recently invented by Jean Hoerni, the integrated circuit of Mister Kilby had about five elements, that could be resistances, condensers, or also transistors. Integrated circuits only became a possibility when Jean Hoerni invented the flat transistor in December 1958. 1952: IBM 700, by International Business Machines, built of vacuum tubes. 1959: integrated circuit with base of silicium and chemical gravure, by Robert Noyce (Fairchild Semiconductor), based on the flat transistor of Jean Hoerni and on the P-N Multiple Semiconductor Junction of Kurt Lehovec. 7,100.00 - $10,100.00 Select options This product has multiple variants. In 1975, Mister Paul Allen and Mister William Bill Gates, founders of Micro-Soft Corporation (name later modified to Microsoft Corporation), began their activities by adapting a Basic dialect to microcomputers. 1985: it is calculated that about 25 000 different programmes exist for microcomputers. 1985: Robert Kahn and Barry Leiner leave DARPA.

December 1966: Lawrence G. Roberts becomes part of DARPA. July 1972: Lawrence G. Roberts added to electronic post the functions "List", "Read selectively", "Save", "Forward" and "Reply", making the Mailto Protocol the most important Arpanet and Internet application until the mid 1990's, with File Transfer Protocol and Telnet Protocol following suit, all of them superated since the mid 1990's only by Hyper Text Transfer Protocol. October 1972: at the International Conference on Computer Communication, Robert Kahn presented Arpanet for the first time to the public, as a network of open architecture with the name of "Interconnected Networks", "Internet" or "Internetting". Uniform Resource Locators for different protocols are explained in Request For Comments 1738. Chargen CSO: The Computing Services Organisation name server interface, also known as PH or QI, which provides names and telephone numbers of university people. Both the Microsoft and IEEE methods for storing single and double precision numbers use respectively 32 bits and 64 vbits, but the bits are organised differently.

1980: 86-DOS, 86 Disk Operating System, of 16 bits (Seattle Computer, based on CP/M-86, another operating system of 16 bits). 1958: first elementary but complete programme for playing chess against a computer, by Doctor A. L. Samuel (International Business Machines). John Mc Carthy (Stanford University), presented the Lisp programming language and the Mc Carthy Test for measuring Artificial Intelligence (playing games, following conversation, receiving information or performing other activities through a terminal). Shortly later appeared the IBM 370 and the Basic Operating System, Tape Operating System and Disk Operating System (unrelated to Basic programming language, or to later DOS operating systems such as PC-DOS, MS-DOS, DR-DOS, et cetera). BASCOM 1.0 was released by IBM in March 1982, first Basic interpreter for the IBM PC, written by Microsoft with code and method developed by Bill Gates, Greg Whitten and others. BASIC Basic is a programming language created by John Kemeny and Thomas Kurtz (Darmouth College) during 1963 and early 1964. It was partly inspired by Dart, an experimental language created on a computer Royal McBee LGP-30 in 1959 by a student of Darmouth College. Since that time some programmers use the term "bug" in reference to different kinds of unexpected programming errors.
