Ans. In 1969, the University of California at Los Angeles and the University of Utah were connected with the beginning of the ARPANET (Advanced Research Projects Agency NETwork) using 56 kbit/s circuits, which is sponsored by the U.S. (United States) Department of Defense (DoD). The goal of this project was to connect computers at different Universities and U.S. defense.
- In the mid-’80s another federal agency, the National Science Foundation (NSF) created a new high-capacity network called NSFnet (National Science Foundation network), which was more capable than ARPANET.
- The only drawback of NSFnet was that it allowed only academic research on its network and not any kind of private business on it.
- Now, several private organizations and people started working to build their own networks, named private networks, which were later (in the 1990s) connected with ARPANET and NSFnet to form the Internet.
- The Internet really became popular in the 1990s after the development of World Wide Web (WWW).
