History of creation and development of the Internet The Internet was born as a result of the confrontation between the USSR and the United States. In America, they believed that the Soviet Union was about to attack them, and then in 1957, the Soviets launched a satellite. Quite the trouble! And they decided in the United States that in case of war, they must have some kind of uninterrupted communication system for early warning of a missile attack. Several universities were assigned to work on a new communication system called ARPANET (Advanced Research Projects Agency Network).

Who invented the Internet and when? When was the Internet born? Robert Elliot Kahn and Vinton CERF are the inventors of the TCP/IP Protocol. In the media, they are often referred to as the"fathers of the Internet". Vinton CERF has held a key position at Google since 2005. They can also be called the fathers of any computer network, because they invented the fundamental Protocol that underlies data transmission.

The first real result was obtained in 1969, on October 29. It was on this day at 9 p.m. that the first successful attempt was made to link the universities at Stanford and in Los Angeles. Operator Charlie Kline in Los Angeles managed to connect to the Stanford computer and transmit the code word.

In the 70s, the network transmitted mostly mail, there were Bulletin boards. At that time, there were already several disparate networks operating in the world, each with its own Protocol. There was a question of unification of the data transfer process. Work in this direction began in 1973. Project Manager Robert Kahn has unveiled several principles for how a shared network should work: Internet connection should not lead to internal alterations; if the information has not reached the addressee, it must be sent again; simple gateways and routers must be used for connection; there is no General network management system.

Internet in the USSR It was a purely scientific channel. The network of the Academy of Sciences began to be formed from it. It was not publicly available. Only researchers could connect to it, but Western scientific libraries with dissertations, monographs, and so on became available to them. In 1989, in the USSR, employees of the Kurchatov Institute and the minavtoprom began to create local networks and help other citizens connect to them.

Period of formation of the world network Popular in the 90s, the Mosaic web browser was developed in 1993 by NCSA. Since 1995, network providers have started routing network traffic, thus freeing up NSFNET University supercomputers for scientific work. At the same time, the W3C world wide web Consortium was created to streamline web standards. since 1996, the WWW Protocol has overtaken FTP in traffic.

In 1994, the SU domain stopped registering new users, as Russia received the RU domain. The SU domain was recommended to be slowly curtailed and eliminated. However, despite the termination of registration and the recommendation to "liquidate", the domain continued to exist semi-legally and slowly develop, until finally, in the 2000s, its activities were fully legalized.

However, each country has set its own Internet Day. In Russia, there are as many as two such days. Runet's birthday is celebrated on April 7. But the Moscow firm it Infoart Stars sent out letters to users with two offers: consider September 30 International Internet day and celebrate it every year; Statistics say that, for example, in 2009, the Internet brought in 1.6% of Russia's GDP (19.3 billion dollars), about the same as Spain or Italy (as a percentage). According to forecasts, in 2015, the contribution of the network economy to Russia's GDP should reach 3.7%.
