Internet history

The Internet originated in the 1969 ARPANET experiment by the US Department of Defense Advanced Research Projects Agency ARPA (now DARPA). ARPANET experiments have demonstrated that packet switching technology is effective for data communication and that data communication on a global scale can be achieved by standardizing the protocol (TCP / IP).

In the mid-1980s, the National Science Foundation (NSF) began supporting the project. In 1990, the original ARPANET was dismantled and led by the NSF network operated by NSF, and LAN servers of research facilities in the world including the United States were connected to this network. Later, this network was opened to commercial networks and developed rapidly.
