Internet:The Internet was the result of some visionary thinking by people in early 1960s who saw great potentiol value in allowing computers to connect and share information on research and development in scientific and military fields. J.C.R Licklider of MIT (Massachusetts Institute of Technology, USA), first proposed a global network of computers in 1962, and moved over to the Defense Advanced Research Projects Agency (DARPA) in late 1962 to head the work to develop it. Leonard Kleinrock developed the theory of packet switching, which was to form the basis of internet connections. Lawrence Roberts connected a Massachusetts computer nwith a California computer in 1965 over dial-up telephone lines. In 1966 Roberts developed his plan for ARPANET (Advanced Research Projects Agency Network). These Dreamers and many more are the real founders of Internet.
E-mail:E-mail was developed for ARPANET in 1972. The @ symbol was chosen from the variable symbols to link the username and address. The Internet matured in the mid of 1970's as a result of the TCP/IP architecture which was developed throughout the 1970's.
in 1989 another significant event took place in making the internet friendly and easier to use. Tim Berners-Lee and others proposed a new protocol for information distribution. This protocol which became the World Wide Web in 1991, was based on hypertext- a system of embedding links in text to link to other portions of text.
As the Internet has become ubiquitous, faster and progressively accessible to non-technical user communities, social networking and collaborative services have grown rapidly; enabling people to communicate and share interests in many more ways. Sites like Facebook, Twitter, Linked-In, YouTube, Flicker and many more allow people of all ages to rapidly share their interests with others everywhere.
