ARPANET
The U.S. Department of Defense’s emerging technology agency, DARPA (Defense Advanced Research Projects Agency), was tasked with developing packet network switchers for military communications use. The first message was sent over the ARPANET (Advanced Research Projects Agency Network) from a computer lab at the University of California, Los Angeles (UCLA) to the second network node at Stanford Research Institute (SRI). UCSB and the University of Utah were connected soon after.
