The computer network is multiple computers connected to each other by using a wired computer in one location in order to exchange information and data with other computer users. Internet begins in 1969, when the united states department of defense, or more commonly called known as DARPA (Defense Advanced Reserch Project Agency) conducted research on how to connect a computer to another so as to form a network.
The existence of a research program and continues called ARPANET. 1 year continues later this study yielded good results with more than ten computers successfully connected to each other so that they can interact and form networks. This research continues to grow rapidly so as ARPANET in 1972 successfully completed the program called email created by Roy Tomlinson for ARPANET. With the results of these this email program, a computer – interconnected computers can send messages among computer to another. This email is easy to be immediately popular. In the same year the icon “@” was also introduced as an important symbol that means “at” or “on”. The ARPANET computer network continues to be developed outside the United States, namely in 1973 and University College in London is the first computer that is a member of the existing ARPANET outside the United States. Two computer experts that Vinton Cert and Bob Kahn in the same year created a very big idea tang became the forerunner of the Internet. The thoughts presented the first time at Sussex University.
In 1981 France Telecom using ARPANET managed to create a buzz remarkable that by launching the first television telephone in the world where someone can call each other while associated with the video link. Computer networks become more and more progress more rapidly, it needed a formal protocol that is recognized by all networks. To homogenize the address with your network, then in 1984 introduced changes to the domain name system that we know today by the name of DNS (Domain Name System). Read more
