In computing, a server is a computer program or a device that provides functionality for other programs or devices, called "clients".

This architecture is called the client–server model, and a single overall computation is distributed across multiple processes or devices.

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.

Network monitoring is the use of a system that constantly monitors a computer network for slow or failing components and that notifies the network administrator (via email, SMS or other alarms) in case of outages or other trouble.
