The Defense Advanced Research Projects Agency (then called just Advanced Research Projects Agency) created ARPANET in 1969. initially consisting of just 4 sites: UCLA (Los Angeles, CA), Stanford Research Institute (Menlo Park, CA), UCSB (Santa Barbara, CA), and University of Utah (Salt Lake City, UT).

The original ARPANET is now the Internet. It no longer exists. The Department of Defense maintains their own, secure network similat to the Internet for defense purposes today.
ARPANET is the computer network developed by the U.S. Department of Defense in 1969 from which the Internetoriginated.
ARPANET (Advanced Research Projects Agency Network)
The internet has its roots in a computer networking system that was established by the US Defense Department's Advanced Research Project Agency. This led to the development of ARPANET which was the first network to use internet protocol.
ARPANET
Internet stands for internal network. When the defense department first figured out how to make their computers "talk" to each other they called it the internal network. As the technology developed for wider uses the name internet stuck.
The internet dates back to ARPANET which was funded by an agency of the the U. S. Department of Defense.The Advanced Research Projects Agency Network(ARPANET), was the world's first operational packet switching network and the core network of a set that came to compose the global Internet. The network was funded by the Defense Advanced Research Projects Agency (DARPA) of the United States Department of Defense for use by its projects at universities and research laboratories in the US. The packet switching of the ARPANET was based on designs by Lawrence Roberts of the Lincoln Laboratory.[1]Sources:http://en.wikipedia.org/wiki/Arpanet
The ARPANET (Advanced Research Projects Agency Network) developed by ARPA of the United States Department of Defense during the Cold War, was the world's first operational packet switching network, and the predecessor of the global Internet.
