A server can be modeled as a physical machine that acts as a server of information on the network, or it might be modeled as a software application that provides these services, and is installed on a computer machine on the network. Use of the Server symbols provided on the Network Concept diagram will vary accordingly.

As a default, the following server symbols are provided on the Network Concept diagram:

A computer that provides services to other computers, or the software that runs on it.

An access server acts as a concentration point for dial-in and dial-out connections.

A computer that hosts files so that they can be accessed or retrieved by other computers on the same network.

A server with a PC router connected.

A network server or a server operating system that provides a Windows or a Linux desktop user interface to other computers. Software programs installed to the Terminal Server can be run from the external machines as if they were installed on that machine itself.

A server equipped with voice recognition and text-to-speech technologies to enable users to access and navigate software on the server by the means of voice.

A computer that serves up a website, accepting HTTP requests from web browser clients.
