A server farm or server cluster is a collection of computer servers maintained by an organization to supply server functionality far beyond the capability of a single device. Modern data centers are now often built of very large clusters of much simpler servers, [ 15 ] and there is a collaborative effort, Open Compute Project around this concept.
A sample network diagram Readily identifiable icons are used to depict common network appliances, e.g. routers, and the style of lines between them indicates the type of connection. Clouds are used to represent networks external to the one pictured for the purposes of depicting connections between internal and external devices, without ...
A host is a node that participates in user applications, either as a server, client, or both. A server is a type of host that offers resources to the other hosts.

Configuration Management (CM) is an ITIL-specific ITSM process that tracks all of the individual CIs in an IT system which may be as simple as a single server, or as complex as the entire IT department. In large organizations a configuration manager may be appointed to oversee and manage the CM process.
Whereas the words server and client may refer either to a computer or to a computer program, server-host and client-host always refer to computers. The host is a versatile, multifunction computer; clients and servers are just programs that run on a host. In the client–server model, a server is more likely to be devoted to the task of serving.
With the Apache web server, for example, this behavior is provided by the mod_autoindex module [9] and controlled by the Options +Indexes directive [10] in the web server configuration files. These automated directory listings are sometimes a security risk because they enumerate sensitive files which may not be intended for public access, in a ...
Others periodically check the configuration files for changes. Users can instruct some programs to re-read the configuration files and apply the changes to the current process, or indeed to read arbitrary files as a configuration file. There are no definitive standards or strong conventions. A configuration file for GNU GRUB being edited.
The @Language directive, the <script language="language" runat="server" /> syntax or server configuration can be used to select the language. In the example below, Response.Write Now() is in an HTML page; it would be dynamically replaced by the current time of the server.
