The internet is a part of our everyday life right now. It has almost come down to food, shelter, clothing & Wifi currently, such is the necessity of the Internet in our lives. It has rejuvenated and revolutionized the whole communication. The empire of computers lay on the concrete base of the online world.
The evolution of the Internet
It all began in the United States in collaboration with France & the United Kingdom. Computer science was emerging in the late 1950s & it began to consider time-sharing between computer users and, later, they tried to achieve the idea of this over wide area networks. Paul Baran came up with a distributed network based on data in message blocks in the early 1960s and Donald Davies proposed packet switching in 1965 at the National Physical Laboratory (NPL) in the UK, which was tested for research for two decades. The U.S. dept of defense initiated contracts in 1969 for the development of the ARPANET project, directed by Robert Taylor and managed by Lawrence Roberts. ARPANET adopted the packet switching technology proposed by Davies and Baran, driven by mathematical work in the early 1970s by Leonard Kleinrock at UCLA. The network was built by Bolt, Beranek, and Newman.
In the 1980s the National Science Foundation-funded national supercomputing centers at many universities in the US and provided interconnectivity in 1986 with the NSFNET project, which created network access to these supercomputer sites for research and academic institutions. International connections to NSFNET, the development of ideas such as the Domain Name System, and the adoption of TCP/IP internationally marked the commencement of the Internet. Commercial Internet service providers (ISPs) emerged in the late 1980s. The ARPANET was dissolved in 1990. Limited private connections to parts of the Internet by officially commercial individuals started in several American cities by late 1989 and 1990. The NSFNET was dissolved in 1995, deleting the last restrictions on the use of the Internet to allow commercial traffic.
Research at CERN in Switzerland by English computer scientist Tim Berners-Lee in 1989-90 gave birth to the World Wide Web, linking hypertext documents into an information system that you can access from any node on the network. From the mid-1990s onwards, the Internet has had an immense impact on culture, commerce, and technology, including the rise of faster communication by electronic mail, instant messaging, voice over Internet Protocol (VoIP) telephone calls, two-way interactive video calls, and the World Wide Web with its interactive forums, blogs, social networking, and online shopping sites. Increasing amounts of data are transmitted at higher and higher speeds over networks operating at 1 Gbit/s, 10 Gbit/s, or more. The Internet’s takeover of the global communication landscape was swift in terms of History: it only connected 1% of the information flowing through two-way telecommunications networks in the year 1993, 51% by 2000, and more than 97% of the telecommunicated information by the end of 2007. Today, the Internet is still growing, driven by the greater impetus of online information, commerce, entertainment, and social networking.
