Also known asArpanet
ARPANET is the computer network born in the United States in 1969 with funding from ARPA, the Department of Defense agency for advanced research projects.
It connected universities and research centres and was the first large packet-switched network (data travels split into small blocks that follow different routes and are reassembled on arrival). ARPANET adopted the TCP/IP protocols, the same ones the internet still runs on today, also thanks to ideas tested in Europe by the French Cyclades network.
Born as a military project, the network was decommissioned on 28 February 1990 and handed over to scientific research and then to civil society: in that shift the internet became a tool for peace, a platform connecting people, ideas and cultures. A few months later, at CERN, Tim Berners-Lee was writing the World Wide Web.

An example
A manufacturing company that networks its plants in two countries uses the same TCP/IP protocols ARPANET adopted, the network where they were first tested on a large scale.
