Client-server architecture (client/server) is a network architecture in which each computer or process on the network is either a client or a server.

Clients are PCs or workstations on which users run applications. Clients rely on servers for resources, such as files, devices, and even processing power. Followings are the example of client-server architecture showing a server connected with multiple clients.
