Where Did the Internet Come From?

The Internet’s origins in the United States began in the 1960s. The Advanced Research Projects Agency (ARPA) of the Department of Defense was doling out a great deal of research money to universities and other research centers around the country. ARPA quickly realized that having some sort of data network that would connect the various research sites would make it much easier for research scientists and ARPA officials to share information.

A great deal of theory related to packet-switching networks was developed (much of this early research was done at MIT) and then tested by ARPA by the late 1960s. Two issues that were of supreme importance in developing the packet-switching network envisioned by ARPA scientists were the protocol that would provide the rules and transmission scheme for data on the network and the devices that would actually switch the data along a particular path as it moved from a sending to a receiving device.
