FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Independently, both developed the concept of what we now know as “packet switching, ” a term Davies coined in 1965. Baran’s term was “distributed adaptive message block switching.” As he put it, “Davies chose a wonderful name.” Packet switching breaks big chunks of data into smaller units, called packets.

Detailed explanation-2: -In late 1969, a team of UCLA graduate students under the leadership of professor Leonard Kleinrock sent the first packet-switched message between two computers.

Detailed explanation-3: -This approach, developed by a series of scientists and engineers in the 1960s, revolutionized the way that digital information was sent along communications lines. Sending data became cheaper and more reliable and flexible than the circuit-switched systems used for telephone communication.

Detailed explanation-4: -1962: Paul Baran of RAND develops the idea of distributed, packet-switching networks. ARPANET goes online in 1969. Bob Kahn and Vint Cerf develop the basic ideas of the Internet in 1973.

Detailed explanation-5: -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.
