How did the Internet?

Internet is a global system consisting ofunited computer networks. Today, with the help of it, an information environment has been formed that covers the entire planet and serves as a physical infrastructure for the World Wide Web. Who is behind the creation of one of the greatest inventions of mankind?

Internet in the usual way for us appearedapproximately in the mid-1990s, but he was initiated by one of the projects of the US Department of Defense (DARPA), launched in 1969. The task of the project was to create an uninterrupted digital connection, provided that there were possible military collisions. For its implementation, the leading American universities have taken.

It is no exaggeration to say that on October 291969 was a turning point in the history of the development of information technology. At 9 pm, a data transfer session was conducted between two computers of the ARPANET network (a prototype of the Internet), one of which was located at the University of California, Los Angeles, and the other at 600 kilometers at Stanford University. The attempt was successful, and it was on this day that you can celebrate the birthday of the Internet.

In 1971, a program was developed forsending and receiving email messages. It became so popular that throughout the 1970s, the network was most often used to work with a mail program (the first mailing lists started to go on) or with a notice board.

On January 1, 1983 the ARPANET network changed the protocolwith NCP (Network Control Program) on TCP / IP, used today. In those years, ARPANET has become so popular that it is this network that is associated with the Internet. Although soon ARPANET had a solid competitor - inter-university network NFSNet, which connected several smaller networks and worked much faster.

In 1989, at CERN (Europeannuclear research) the idea was born and the concept of the World Wide Web was developed, that is, the transfer of hypertext documents via the Internet - the World Wide Web. The merit in her invention belongs to the British scientist Tim Berners-Lee. It is called the "father" of the modern Internet. He also began developing the Http protocol and the HTML programming language. Already just around the corner was the writing of a graphic protocol for the development of hypertext browsers, and they are known to have made the Internet widely and easily accessible.

In 1990, the ARPANET network fell into oblivion, losingon all fronts of NSFNET. In the same year, the first successful attempt was made to connect to the network using a telephone set. In 1991, web technologies became widely available, and today they are used, according to various estimates, from 1 to 1.5 billion people, that is, every fifth inhabitant of the Earth.
