Sometimes this dual usage can lead to confusion, for example in the case of a web server. This term could refer to a machine dedicated to websites, and it used in this sense by companies offering commercial hosting facilities. Alternatively, web server could refer to software such as the Apache HTTP server, which runs on such a machine and manages the delivery of web page components in response to requests from browser clients.

Server hardware

A Server computer shares its resources, such as peripherals and file storage with the users' computers, called clients, on a network. It is possible for a computer to be a client and a server simultaneously, by connecting to itself in the same way a separate computer would.

Many new devices now come with server capabilities. The X-Internet, Web Services, and Microsoft's .NET initiative all work to make even the smallest system a server.

Many large enterprises employ numerous servers to support their needs. A collection of servers in one location is often referred to as a server farm.

Server operating systems

The rise of the microprocessor based server was facilitated by the development of several versions of Unix to run on the Intel microprocessor architecture, including Solaris, Linux and FreeBSD. The Microsoft Windows series of operating systems also now includes server versions that support multitasking and other features required for servers, beginning with Windows NT.

Historical note

Mainframes and minicomputers were originally accessed using dumb terminals, which were unable to carry out any significant processing. This largely ended with the widespread use of personal computers by users.
