Communication as a matter of national survival. So in 1975, the Department of Defense United States tended experimental computer network, ARPANET, the ancestor of what we now know as the Internet. No bomb devastated the , as we well know, but the interest in computer networks is not diluted and, better still, he moved to a more peaceful and fertile territory, universities. At the beginning of the last decade of the twentieth century, Tim Berners-Lee was working for the European Organization for Nuclear Research (CERN for its French name). Facilitate the exchange of data, results and news from the scientists, give them a useful computer tool agilisima, such was the purpose of Berners-Lee. In 1991, British mathematician invented the first browser, the WorldWideWeb (or, as he is known more commonly,). What was his invention? Well, in a kind of lingua franca computer, which crossed the transfer of large amounts of information from one computer to another.

Thanks to the (the program), this was the birth of the Internet (physical network). The web addresses, see an acronym that summarizes the contribution of Berners-Lee: (Hypertext Transfer Protocol). Key concept here, Hypertext means peaceful coexistence, on a support, multi-user resources managed according to your mood or needs. (Hypertext is a step forward, if you will, on the notion of interface, abstract those borders, within a computer program, allowing the orderly coexistence of dissimilar files.) It is not irrelevant to consider the web as a giant hypertext. In the first instance, from the website of the CERN, Lee and his colleagues tried to keep a list of suppliers and available information.
