The origin of the Internet?

1. Network (Internet), which was formerly the communications network used by the U.S. Defense Advanced Research Projects Agency (ARPA) for military purposes. In the late 1960s, we were in the middle of the Cold War. At that time, the U.S. military built a military network, called ARPAnet, by the Defense Department's Advanced Research Projects Agency (ARPA), in order to keep its computer network in contact even if part of the network was destroyed in the event of an attack.

2. ARPANET was opened in 1969 with just four computers, allowing scientists to experiment with computer networking, the precursor to the Internet. In the 1970s, ARPAnet developed arbitrarily and set up new research projects, which eventually formed the "Internet". Researchers called it "the Internet" for short, and the term has stuck ever since.
