COMPUTER NETWORKING

Detailed explanation-1: -ARPANET, in full Advanced Research Projects Agency Network, experimental computer network that was the forerunner of the Internet. The Advanced Research Projects Agency (ARPA), an arm of the U.S. Defense Department, funded the development of the Advanced Research Projects Agency Network (ARPANET) in the late 1960s.

Detailed explanation-2: -The first workable prototype of the Internet came in the late 1960s with the creation of ARPANET, or the Advanced Research Projects Agency Network. Originally funded by the U.S. Department of Defense, ARPANET used packet switching to allow multiple computers to communicate on a single network.

Detailed explanation-3: -The U.S. Advanced Research Projects Agency Network (ARPANET) was the first public packet-switched computer network. It was first used in 1969 and finally decommissioned in 1989. ARPANET’s main use was for academic and research purposes.

Detailed explanation-4: -Bob Kahn and Vint Cerf American computer scientists who developed TCP/IP, the set of protocols that governs how data moves through a network, which helped the ARPANET evolve into the internet we use today. Cerf is also credited with the first written use of the word ‘internet’.
