The servers in a network perform a variety of complex tasks. Servers for large networks have become specialized to accommodate the expanding needs of users.   The following are some examples of the different types of servers included on many large networks:   File and Print Servers File and print servers provide file and printer resources from a centralized location. When a client sends a request for data to the file and print server, the entire database or file is downloaded to the computer making the request. For example, when you open a word-processing application, the application runs on your computer and the document stored on the file and print server is loaded into your computer’s memory so that you can edit or use the document locally. Once the document is saved back on the server, anyone on the network who has the proper access, or permission, may look at the file. In other words, file and print servers are used to store and retrieve centralized file and data records.   Database Servers Database servers can store large amounts of data in a centralized location and make this data available to users so that they do not need to download the entire database. With a database server, the entire database stays on the server and only the results of a request are downloaded to the computer making the request. For example, you might use a client application that runs locally, such as Microsoft Access, to search an employee database for the names of all employees born in November. The employee database is stored on a database server, such as Microsoft SQL Server™. When the server processes your request, only the result of your query (the list of November birth dates) is downloaded from the server onto your local computer.   Mail Servers Mail servers operate like database servers in that there are separate server and client applications, with data selectively downloaded from the server to the client. Mail servers manage the e-mail services for the network.   Fax Servers Fax servers manage fax traffic into and out of the network by sharing one or more fax modems. This makes a fax service available to anyone on the network without having to install a fax machine on everyone’s computer.   Directory Services Servers Directory services servers provide a central location to store information about the network, including the identity of the users accessing the network and the names of the resources available in the network. This  enables network security to be administered centrally. An administrator can define a resource, such as a printer, and the type of access that users have to that resource. After the administrator defines the resource, users can locate the resource and use it, depending on the type of access assigned to them.
