    PDP-11 based front-end processor around 1975. A front-end processor (FEP), or a communications processor, is a small-sized computer which interfaces to the host computer, a number of networks, such as SNA, or a number of peripheral devices, such as terminals, disk units, printers and tape units.

    A Boolean circuit can be seen as a computer network: each gate is a computer that runs an extremely simple computer program. Similarly, a sorting network can be seen as a computer network: each comparator is a computer. Distributed algorithms in message-passing model. The algorithm designer only chooses the computer program. All computers run ...

  7. Client–server model - Wikipedia

    en.wikipedia.org/wiki/Client–server_model

    A host is any computer connected to a network. Whereas the words server and client may refer either to a computer or to a computer program, server-host and client-host always refer to computers. The host is a versatile, multifunction computer; clients and servers are just programs that run on a host. In the client–server model, a server is ...

    The first part he implemented was the chat part, which he did with borrowed parts written by his friends Jyrki Kuoppala and Jukka Pihl. The first IRC network was running on a single server named tolsun.oulu.fi. [7] Oikarinen found inspiration in a chat system known as Bitnet Relay, which operated on the BITNET. [8]
