ARPANET access points in the 1970s. The Advanced Research Projects Agency Network (ARPANET) was the first wide-area packet-switched network with distributed control and one of the first computer networks to implement the TCP/IP protocol suite. Both technologies became the technical foundation of the Internet. The ARPANET was established by the ...
The Network Control Protocol (NCP) was a communication protocol for a computer network in the 1970s and early 1980s. It provided the transport layer of the protocol stack running on host computers of the ARPANET, the predecessor to the modern Internet. NCP preceded the Transmission Control Protocol (TCP) as a transport layer protocol used ...
The ARPANET pioneered the creation of novel encryption devices for packet networks in the 1970s and 1980s, and as such were ancestors to today's IPsec architecture, and High Assurance Internet Protocol Encryptor (HAIPE) devices more specifically. DuPont and Fidler provide a historical perspective of ARPANET encryption devices in the broader ...
Ray Tomlinson. Raymond Samuel Tomlinson (April 23, 1941 – March 5, 2016) was an American [1][2][3][4] computer programmer who implemented the first email program on the ARPANET system, the precursor to the Internet, in 1971; [5][6][7][8] It was the first system able to send mail between users on different hosts connected to ARPANET.
The ARPANET expanded rapidly across the United States with connections to the United Kingdom and Norway. Several early packet-switched networks emerged in the 1970s which researched and provided data networking. Louis Pouzin and Hubert Zimmermann pioneered a simplified end-to-end approach to internetworking at the IRIA.
In 1971 the first ARPANET network mail was sent, introducing the now-familiar address syntax with the '@' symbol designating the user's system address. Over a series of RFCs, conventions were refined for sending mail messages over the File Transfer Protocol. Several other email networks developed in the 1970s and expanded subsequently.
Creeper was an experimental computer program written by Bob Thomas at BBN in 1971. [2] Its original iteration was designed to move between DEC PDP-10 mainframe computers running the TENEX operating system using the ARPANET, with a later version by Ray Tomlinson designed to copy itself between computers rather than simply move.

Larry Roberts (December 21, 1937 – December 26, 2018) was an American computer scientist and Internet pioneer.. As a program manager and later office director at the Advanced Research Projects Agency, Roberts and his team created the ARPANET using packet switching techniques invented by British computer scientist Donald Davies and American engineer Paul Baran.
