The first connection on what would become the Internet was made on this day when bits of data flowed between computers at UCLA and the Standford Research Institute. This was the beginning of ARPANET, the precursor to the Internet developed by the Department of Defense. 

Originally funded by the U.S. Department of Defense, ARPANET used packet switching to allow multiple computers to communicate on a single network. The technology continued to grow in the 1970s after scientists Robert Kahn and Vinton Cerf developed Transmission Control Protocol and Internet Protocol, or TCP/IP, a communications model that set standards for how data could be transmitted between multiple networks. ARPANET adopted TCP/IP on January 1, 1983, and from there researchers began to assemble the “network of networks” that became the modern Internet.
