A British physicist’s frustration with varied data formats and computers coming to the European Organization for Nuclear Research (CERN) laboratory in Switzerland from different countries in 1989 launched a revolution that today’s generation takes for granted. Tim Berners-Lee invented the World Wide Web in 1990 and published the first website on August 6, 1991 with the address http://info.cern.ch, giving shape to a single information network. A common hypertext language, inter connectivity, and the sea of data it has created in two decades are testimony to its profound impact.
Today, we cant live without internet . www has become a way of life. The Internet is a global system of interconnected computer networks that use the standard Internet Protocol Suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies.
The Internet is defined as a worldwide interconnection of computers and computer networks that facilitate the sharing or exchange of information among users.
The Internet has no centralized governance in either technological implementation or policies for access and usage; each constituent network sets its own standards. Only the overreaching definitions of the two principal name spaces in the Internet, the Internet Protocol address space and the Domain Name System, are directed by a maintainer organization, the Internet Corporation for Assigned Names and Numbers (ICANN). The technical underpinning and standardization of the core protocols (IPv4 and IPv6) is an activity of the Internet Engineering Task Force (IETF), a non-profit organization of loosely affiliated international participants that anyone may associate with by contributing technical expertise.
