History of Internet:-

Internet was created way back in 1969, during the Cold War, by the United States military and moved over to the Defence Advanced Research Projects Agency (DARPA) in late 1962 to head the work to develop it. It was meant to be a "nuke-proof" communications network. Today, the Internet spreads across the globe and consists of countless networks and computers, allowing millions of people to share information. Data that travels long distances on the Internet is transferred on huge lines known collectively as the Internet backbone.
