The second reason is that the computer networking community is a strong participant in the open-source move-ment. One of the first uses of the term protocol in a data-commutation context occurs in a memorandum entitled A Protocol for Use in the NPL Data Communications Network written by Roger Scantlebury and Keith Bartlett in April 1967.. On the ARPANET, the starting point for host-to-host communication in 1969 was the 1822 protocol, which defined … .

Thus, a host is the end point of communication in the Internet and where a communication starts. The following diagram shows a person is logged in to computer A, and from there, he remote logged into computer B.Telnet is an application layer protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection.
