• TCP: In 1973, Vinton Cerf and Robert Kahn designed the TCP (Transmission Control Protocol). This was a major improvement over the NCP (Network Control Program).
• Ethernet: In 1973, Bob Metcalfe managed to develop the first Ethernet. By the eighties, it became vastly popular due to its adaptability to low-cost wiring.
The term “packet switching” for this mode of data transfer was first used by Donald Davies in 1965. Before that, Baran referred to the data packets as “message blocks”. Data transmission thus became more flexible with each packet having information about its own destination and a predestined route was no longer required. Davies’ conceptions on the topic were put forth during a conference in Edinburgh on 5 August 1968.
