ARPANET was an important stage in technology and helped bring forth the
Internet. The history of the Internet is becoming more important to
know, especially in computer science courses. ARPANET paved the way for
communications across multiple computers, and eventually long distances.
The basics of ARPANET supply the backbone for the technology we still
use today to send data around the world almost instantly.
RPANET was developed by the Advanced Research Projects Agency (ARPA) of
the United States. The agency was later renamed Defense Advanced
Research Projects Agency (DARPA), and is part of the Department of
Defense. The agency was tasked with building and creating future
technologies, and many of the ones we use today originate from this
group. As this was the first network of its type, it was named after the
agency, thus ARPA Network. It was later called ARPANET to differentiate
it from other networks in development around the world.
