The experiment is a success, but it shows that available telephone lines are still inadequate, confirming Leonard Kleinrock's proposal for packet interchange instead of circuits. However, Finger can still be seen in Unics Work Stations. Created by Kenneth Thompson and Dennis Ritchie (Bell AT & T), who were unhappy with Multics, Unics became one of the first time-sharing operating systems. 1970 to 1972: the Learning Research Group assembled by Xerox at the Palo Alto Research Centre produces the "Alto", first operating system that featured icons in a graphic interface, as opposed to text line in a command prompt. August 1968: after Lawrence G. Roberts and his DARPA group had defined the specifications for Arpanet, a group led by Frank Heart (Bolt Beranek) and by Newman (B. Network measuring system falls under the responsibility of Leonard Kleinrock and his group of the University of California at Los Angeles. 1981: Xerox Star, graphic operating system by Xerox at Palo Alto Research Centre. Days later, the Human Intellect project of Douglas Engelbart (that included NLS, a forerunner of hyper text) is installed at the Stanford Research Institute, becoming the second computer host-server.

Snobol: a programming language used from the 1960's to the 1980's. Speed Coding: the second scientific programming language, created by Seldon and John Backus of International Business Machines in 1953. SGML, Standard Generalised Mark-up Language: the basic standard from which most mark-up languages are derived. 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". 1958: first elementary but complete programme for playing chess against a computer, by Doctor A. L. Samuel (International Business Machines). July 1958: system of time sharing is proposed at the Massachussetts Institute of Technology to substitute batch processing. 1958: Advanced Research Projects Agency begins studies for a military Arpa Network, that in time would become the origin of the Interconnected Networks (also known as Internetting or Internet). An Internet Protocol of 32 bits was thus devised, the first 8 bits defining the network and the other 24 bits defining the host inside that network, giving a maximum of only 256 possible networks. 1964: Leonard Kleinrock publishes a book on the theory of packet interchange for computer networks. 1964: essay on the application of packet interchange for secret military communications, by Paul Baran and others (R.

At the same event, Donald Davies and Roger Scantlebury (Nuclear Physics Laboratory, in Great Britain) also present a project on a computer network based on packet interchange. The new protocol was applied to Arpanet, Packet Radio and Packet Satellite. It became obvious that the addressing system of Network Control Protocol, based on the Interface Message Processor of Arpanet, was insufficient for an open network, and therefore another protocol with control of transmission errors should eventually have to be devised. Control of flux from host to host. The four host servers (U. 1960: first joy stick for playing action games, built in a wooden box by two students of the Massachussetts Institute of Technology. August 1962: essay on a "Galactic Network" of computers, by J. C. R. Licklider (Massachussets Institute of Technology). 2nd September 1969: first short distance message transmitted between two computers, both inside of U. C. L. A. and connected by a 5 metre cable, by Leonard Kleinrock. 1969: Unics operating system. 1969: Request for Comments, method developed by S. Crocker (U. 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.

The computers interchanged meaningless data while about twenty people watched the historical event, which MARKS THE START OF INTERNET. 1970: it is calculated the existence of about 100 000 computers in the world. 1960: it is calculated the existence of about 5 000 computers in the world. 1960: Mac Project, first computer network. It had an integrated floating decimal point mathematic co-processor for the first time in x86 history. When a QuickBasic 4.0 programme was run in an IBM PC equipped with a mathematic co-processor, what is billiards floating point mathematics was performed very quickly indeed. By the time that QuickBasic 4.0 had been released in late 1987, maybe half a million copies of QuickBasic were already in use world-wide. It makes possible the insertion of elements to form an integrated circuit, as it had been proposed by G. W. A. Dummer in 1952. Integrated circuits gradually substituted printed circuits as main computer processors, although printed circuits remained in use for simpler purposes.
