host
(I) General computer network usage: A computer that is attached to
a communication subnetwork or internetwork and can use services
provided by the network to exchange data with other attached
systems. (See: end system.)
(I) Specific Internet Protocol Suite usage: A networked computer
that does not forward Internet Protocol packets that are not
addressed to the computer itself. (See: router.)
(C) Derivation: As viewed by its users, a host "entertains"
guests, providing application layer services or access to other
computers attached to the network. However, even though some
traditional peripheral service devices, such as printers, can now
be independently connected to networks, they are not usually
called hosts.
