Meaning – The term server, refers to a functional unit that provides services to one or more clients over a network. Examples include a file server, a print server, and a mail server.

In computing, a server is a piece of computer hardware or software (computer program) that provides functionality for other programs or devices, called “clients”. This architecture is called the client-server model. Servers can provide various functionalities, often called “services”, such as sharing data or resources among multiple clients or performing computation for a client.

A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.

Example of usage“Client-server systems are today most frequently implemented by (and often identified with) the request-response model: a client sends a request to the server, which performs some action and sends a response back to the client, typically with a result or acknowledgment. Designating a computer as “server-class hardware” implies that it is specialized for running servers on it.”
