J.C.R Licklider was the first person in 1962 who put through the concept of Galactic Network which stated the possibility of an interconnected set of computers at a Global level through which people could access data and programs from any site. In response to the launch of the Sputnik in 1957, the first earth satellite launched by the Russians the United States formed the Advanced Research Projects Agency (ARPA) along with the Department of Defense (DOD) to work on scientific and technological advances for the military.

Robert Lawrence was hired by ARPA to create a network based on the vision of J.C. R. Licklider; Lawrence created the network based on the idea of packet switching. The ARPANET was developed in 1969 which enabled connectivity between four points namely the University of California at Los Angeles, Stanford Research Center, University of Utah and the University of California at Santa Barbara. In 1973 a networking protocol called TCP/IP was developed which enabled communication and interconnectivity across diverse networks and this replaced the Network control protocol used by the ARPANET.

The ARPANET was replaced by the NSFNET which in turn was connected to the CSNET (Computer science Network) and the EUNET (European Network) which respectively connected American Universities and Research facilities in Europe. The World Wide Web was released and first Internet society was formed in 1992. The Internet started gaining popularity in the 1990’s and it is practically impossible now to imagine life without the Internet.
