- Client-host and server-host have subtly different meanings than client and server. 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 user-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 more likely to be devoted to the task of serving.

Network Configuration Files The /etc/hostname file contains the fully qualified domain name of the local host. Thus, the system emu, in the DNS domain cassowary.net, has the fully qualified domain name emu.cassowary.net. Independent of DNS is the local hosts file (/etc/hosts), which is used to list local hostnames and IP addresses. For a network with large numbers of hosts, using the /etc/hosts file is problematic because its values must be updated on every host on the network each time a change is made.
