The ARPANET's creators had relatively little hands-on experience with Telnet and file transfer apps. The ICCC demo could conceivably flop, but if it worked, "it would prove the network was not ...

The resulting network was called Arpanet, and the first packets of data traversed the network in September 1969. A CDC 7600 mainframe computer fills an entire room at Lawrence Livermore National ...

This saw three different types of network, Arpanet, the satellite network Satnet, and PRNET, a packet-radio network using radio transmissions from mobile vans, all connected using the same common ...

But we still need some controls to keep the network functional. Also, since the Arpanet was relatively small, we could experiment with major changes in design, protocols, and more. That would be ...

Thomas wrote Creeper using a PDP-10 assembly and ran it on the existing TENEX operating system, a program that BBN developed in 1969. Using the ARPANET network, Creeper would jump onto a computer ...

As ARPANET grew in size, more computers began to join its network. The need for an agreed set of rules for handling data became paramount. In 1974, American scientists, Vint Cerf and Bob Kahn ...

With ARPANET multiple computers were able to communicate with one another on a single network. ARPANET delivered its first message on October 29, 1969, from one computer located at the University ...

From top: Schematics outlining the Arpanet; a ladder Kleinrock uses to reach the top of a nine-foot whiteboard; the logbook for the first message sent on the network.

NSFNET used Transmission Control Protocol (TCP) and the Internet Protocol (IP) as its communications protocols, borrowed from ARPANET, Mambretti notes, and the network used routers to connect ...
