The Internet has brought a new revolution in the world of computers and communication. The inventions of the telegraph, telephone, radio, and computer set the stage for this unprecedented ability.
Birth of ARPANET:
Scientists and military experts were particularly concerned about what might happen in the event of a Soviet attack on the nation’s telephone system. They were afraid that just one missile could destroy entire network lines and wires.
In 1962, M.I.T. And one of ARPA Scientists J.C.R. Licklider proposed a solution to this problem: a “Galactic Network” of computers in which computers could talk to each other. With such a network they will be able to communicate even if the Soviet Union destroys their telephone system.
In 1965, another M.I.T. scientist developed a method of sending information from one computer to another, which he called “Packet Switching”. Packet breaks the data into blocks or packets before sending Switching to its destination.
These packets used to reach their destinations by different routes. Without packet switching, this government computer network — now known as ARPAnet — was easy prey to enemy attacks, just like the phone system.
In 1969, ARPAnet delivered its first message: a “node-to-node” communication from one computer to another (the first was in a research lab at UCLA and the second was at Stanford, both of which were the same size as a home ). The message LOGIN was short and simple, but it crashed in ARPA’s network and the Stanford computer only received the first two letters of the note.
By the end of 1969, only four computers were connected to ARPAnet, but the network grew rapidly during the 1970s. In 1971, he added ALOHAnet from the University of Hawaii, and two years later networked London’s University College, Norway, and Royal Radar Establishment.
As packet-switched computers grew in networks, it then became more difficult for them to integrate them into a worldwide “Internet”.
In the late 1970s, a computer scientist named Vinton Surf began to solve this problem by developing a way for all computers in the world’s mini networks to communicate with each other. He named his invention the “Transmission Control Protocol,” or TCP. (Later, he added an additional protocol, called the “Internet Protocol”. The references we use today are TCP / IP.)
World Wide Web:
Internet History in Hindi Surf’s protocol transformed the Internet into a worldwide network. During the 1980s, researchers and scientists used it to send files and data from one computer to another.
However, in 1991 there was again a revolution on the Internet. That year, a computer programmer named Tim Berners-Lee from Switzerland started the World Wide Web: an Internet that was not just a way of sending files from one location to another but was itself the “web” of information. Berners-Lee created the Internet we know today.
Since then, the Internet has changed in many ways. In 1992, a group of University of Illinois students and researchers developed a sophisticated browser, which they called Mosaic. (It later became Netscape.) Mosaic K offered a user-friendly way to search the web: This allowed users to view text and images on the same page for the first time and use scrollbars and clickable links Got permission to navigate to. In the same year, the government decided that the Web could be used for commercial purposes. And after this, e-commerce started using the Internet to sell its service and goods directly to the customers.
