In computing, the specialized machine that is in charge of processing requests and delivering data over a network connection is commonly referred to as a server. Servers are essentially designed with extra hardware such as high processing speed, lots of external memory (RAM), added data store capacity (hard disks), and additional features.

In the client/server programming model, a server is an instance of a computer program that renders services to another program on a local area network (LAN) or a wide area network (WAN) over the Internet, which may be working in the same or other computers. Servers such as   Dell PowerEdge R840 is known to be dedicated, meaning that they do no other tasks asides their server tasks. A particular application in a computer may operate as a client with demands for services from other programs and also as a server of demands from other programs.

Network Server

This is a computer in Network that is designated to provide one or more network service. For example file server, database server etc.

A network server is a specialized computer that works as a central repository of data and programs and the entire computer across a network connection to it and makes requests.

A network server has the same hardware as a workstation, but they vary in their functions and use. Network servers help ease the workload for system administrators.

Any network security and configuration can apply to a network server rather than individually passing to various computers connected to the network.

A network server designed to provide one particular service is known as a dedicated server.
