ARPANET – The Internet was originally conceived of and funded by the Advanced Research Projects Agency (APRPA) (now known as the U.S. Department of Defense) in the 1960s. ARPANET (Advanced Research Projects Agency Network) was one of the world’s first “ineternetworking” networks to transmit packets of information via a computer link. Derek S.
