Contributions to computer networks were made by the following:
CERN in Switzerland
The first computer network was created at CERN the European research center for particle physics. it is in Switzerland.
UCLA in 1969
The previous comment "the first computer network was created at CERN" is not correct. In 1989, CERN added the WWW as a new feature to the already-existing internet. The Internet itself was created in 1969 at UCLA. There were previous experiments in wide-area networking, e.g., in 1965. For more info, see "history of the internet" on isoc.org.
DARPA
The computer networking revolution began in the early 1960s and has led us to today internet technology. The Internet was first invented by DARPA (Defense Advanced Research Projects Agency) for military purposes, and then expanded to the purpose of communication among scientists. In 1957, the launch of Sputnik had spurred the U.S to create a network for communications links between military and university computers that would not be disrupted by bombs or enemy spies. In order to solve the problem, in 1968 DARPA (Defense Advanced Research Projects Agency) made contracts with BBN (Bolt, Beranek and Newman) to create ARPANET (Advanced Research Projects Agency Network).
Sergei Lebedev in the Ukraine
The first computer network in Ukraine by Sergei Lebedev for the USSR antimissile system. The system was operational in 1960 far before the idea of ARPANET.
SAGE air defence computer network
A network of vacuum tube computers connected by leased telephone lines and the first MODEMs used by the US to protect against bomber attacks. The system was operational in 1958.
the computer was invented in 1979 by apple
Computer act as end devices between whom the communication is established by networking process.
It is said that the first alphabet was created by thePhoenicians.They were a tribe in theancienttimes.
