As opposed to a peer-to-peer network, a client-server network connects at least one designated server (a computer that provides a networked service) with at least one client computer (service requester and recipient). The server typically provides a variety of services, including file sharing, network security, email access, Web access, printing, etc.
An arrangement where some programs, files or other resources are located on one computer, called the server, but are available to other systems on the network, called clients.
A system in which software is split between server tasks and client tasks. A client sends requests to a server, according to some protocol, asking for information or action, and the server responds. There may be either one centralized server or several distributed ones.
