Internet history

SHARE WITH FRIENDS:

Everyone has heard of the Internet and wants to use it. It is known that the Internet allows you to transmit information over long distances in seconds. Therefore, this course provides information on the origin of the Internet, its structure, the rules by which information is transmitted and received. The history of the Internet is changing and a huge amount of information about the evolving world or society in various forms is being collected in almost every country in the world. Using this information would require a great deal of money and time without the tools of modern information technology. Such problems were solved with the establishment of the Internet (International Information Network). The Internet is a product of the Cold War. Its creation was based on the ARPANet communication network, developed by the US Department of Defense in the early 70s of the twentieth century, as an experimental communication system designed to work even in partial damage from nuclear shocks. ARPANet is a communication package that allows you to automatically bypass broken communication links and exchange information between computers on the network. When the ARPANet was first launched, information was exchanged between 4 computers via a special cable for only 2 minutes. At first, the network was considered secret. Later, when it became possible to exchange information via modem and telephone network, various enterprises and organizations were connected to this network. Thus, this network has become the Internet. The Internet is not affiliated with any organization, but is funded by governments, academic and educational institutions, commercial structures, and millions of individuals. The network is managed by an “Internet Architecture Council” set up by invited volunteers.

The Internet is a collection of thousands of computer networks located around the world and connected to a single network. The exchange of information on the Internet is based on standard rules. The rules of data transmission on the Internet are called protocols (for example, TCP / IP - TRANSMISSION CONTROL PROTOCOL / INTERNET PROTOCOL). The method of data transmission of the TCP / IP protocol is as follows: The TCP protocol divides information into packets; All packets are transmitted to the receiver via the IP protocol and all packets are checked for acceptance by the TCP protocol; Once all packets are received, the TCP protocol organizes them and makes them integrated. Due to the creation and development of a device called a modem (1979 by Nayes) that allows computers to send information over telephone networks, millions of people with only a personal computer and phone Today, the Internet is becoming one of the most important tools of modern business in the study of the world market and the organization of trade. The Internet is not only a network of interconnections or data exchange, but also a set of existing databases that make up the world's knowledge repository. An important difference between the Internet and computers is that it can store information about itself. , it is called the World Wide Web.The creation of the World Wide Web was based on a 1992 project of the European Nuclear Research Council in Switzerland. The aim of this project was to search for effective ways of disseminating information on the Internet and to monitor its consequences. Today, the World Wide Web is one of the fastest growing areas of the Internet. Many people understand the World Wide Web (abbreviated Web or WWW) as the Internet. In fact, the World Wide Web is part of the Internet, meaning an international spider web. The World Wide Web has quickly gained the attention of users due to its richness in multimedia (multimedia - a technology that combines image and textual information with information consisting of sound and moving forms).
