All articles are regularly reviewed and updated by the HISTORY.com team. To this end, a project was devoted to networking computers from various university research institutions. This capability was particularly valuable for software developers, who could distribute their programs to other researchers for testing and debugging. This was the first public demonstration of packet switching. What ARPANET could not do was talk to any of the other computing networks that inevitably sprang up in its wake. Just one missile, they feared, could destroy the whole network of lines and wires that made efficient long-distance communication possible. The client-server protocol makes it possible to access another computer via a remote connection. These interface message processors (IMPs) were smaller (in relation to computers that took up a whole room in those days) machines that provided interoperability in the network. That year, a computer programmer in Switzerland named Tim Berners-Lee introduced the World Wide Web: an internet that was not simply a way to send files from one place to another but was itself a web of information that anyone on the Internet could retrieve. At the time of Klines first message to Stanford, logging into a remote computer was one of just three tasks possible on ARPANET; the other options were printing to a remote printer and transferring files between computers. Several participants share the same channels and send their parcels using them on absolutely equal footing. By doing so, computer vendors did not have to worry about. In contrast to corporate networks, no private communication network is required. An IMP was a ruggedized Honeywell DDP-516 minicomputer with special-purpose interfaces and software.
