The Internet is the global system of interconnected computer networks that uses the Internet protocol to link billions of devices worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web, electronic mail, voice over IP telephony, and peer-to-peer networks for file sharing. Introduction

History A fter the launch USSR first artificial satellite, in 1957, the department of defense in the USA began a development of the system for data transfer . The Defense Advanced Research Projects Agency of the USA initiated creation of a computer network.

Слайд 4

The development of such a network was entrusted to the University of California in Los Angeles, Stanford, University of Utah and University of California at Santa Barbara. Computer network was named ARPANET, in 1969 in the framework of the project the network has united four specified scientific institutions. October 29, 1969, the session was conducted between the first two nodes of the network ARPANET. The session

Joseph Carl Robnett Licklider - was an American psychologist and computer scientist who is considered one of the most important figures in computer science and general computing history. He is particularly remembered for being one of the first to foresee modern-style interactive computing and its application to all manner of activities; and also as an Internet pioneer with an early vision of a worldwide computer network long before it was built. He did much to actually initiate this by funding research which led to much of it, including today's canonical graphical user interface, and the ARPANET, the direct predecessor to the Internet.

Paul Baran - was a Polish-born American engineer of computer networks. He was one of the two independent inventors of packet switched computer networking , and went on to start several companies and develop other technologies that are an essential part of modern digital communication . A nd also as an Internet pioneer with an early vision of a worldwide computer network long before it was built. Paul Baran

By 1971, he developed the first program for sending e-mail across the network. This program immediately became very popular. In 1973, the network was connected via a transatlantic telephone cable to the first foreign organizations from the UK and Norway , so the network became international. January 1, 1983 the ARPANET switched from the NCP Protocol to TCP/IP which is successfully applied until now to combine (or, as they say, "layering") networks. In 1983 the term "Internet" stuck in the ARPANET. Network evolution

In 1988, a Protocol developed Internet Relay Chat (IRC), thanks to which the Internet made possible the real-time communication (chat). In 1989 in Europe, was born the concept of the world wide web. It was suggested by the famous British scientist - Tim Berners-Lee. H e developed the Protocol HTTP, language HTML and identifiers URI . In 1995, the world wide web became the main supplier of information.

Sir Timothy John Berners-Lee - is an English computer scientist, best known as the inventor of the World Wide Web. He made a proposal for an information management system in March 1989 , and he implemented the first successful communication between a Hypertext Transfer Protocol (HTTP) client and server via the Internet.

Today Internet has almost 3 billion subscribers in more than 200 countries. Monthly the size of the network increases by 7-10%. Internet forms the core that provides communication of various information networks. In addition, Internet provides unique opportunities for cheap, reliable and confidential global communications around the world. Thinking about future, there is an interest of connecting to the Internet networks without using the IP Protocol. Currently, the Internet uses almost all known communication lines from low-speed telephone lines to high speed digital satellite channels. Conclusion
