Application Servers
An application server is a type of server designed to install, operate and host applications and associated services for end users, IT services and organizations. It facilitates the hosting and delivery of high-end consumer or business applications, which are used by multiple and simultaneously connected local or remote users.
Communication ServersA communications server is a computing system platform that is used for various network communication applications and allows vendors to add multiple values at different levels of architecture.
Domain controllers/directory Servers
A domain controller (DC) is a server that responds to security authentication requests within a Windows Server domain. It is a server on a Microsoft Windows or Windows NT network that is responsible for allowing host access to Windows domain resources.
Fax Servers
A fax server is a system capable of receiving incoming faxes, sending faxes and distributing faxes over a computer network. Software applications for most operating systems are also available to make a computer in a network act as a fax server. The incoming fax messages can be stored in any printable file format such as graphics or word processing. A fax server helps in reducing the number of dedicated fax lines needed in an environment or organization.
File Servers
In the client/server model, a file server is a computer responsible for the central storage and management of data files so that other computers on the same network can access the files. A file server allows users to share information over a network without having to physically transfer files by floppy diskette or some other external storage device. Any computer can be configured to be a host and act as a file server. In its simplest form, a file server may be an ordinary PC that handles requests for files and sends them over the network. In a more sophisticated network, a file server might be a dedicated network-attached storage (NAS) device that also serves as a remote hard disk drive for other computers, allowing anyone on the network to store files on it as if to their own hard drive.
Print Servers
A print server is a computer that can process print-related jobs on a network of computers. Print servers are connected to a computer network in order to serve the need for printing jobs in a network that may contain more than one printer. A print server usually allows users in a computer network to perform a printing job without having to move files to the computer connected directly to the printer.Also known as printer server or network printer, (although the latter is actually one of the properties of the print server).
Mail Servers
An email server, or simply mail server, is an application or computer in a network whose sole purpose is to act as a virtual post office. The server stores incoming mail for distribution to local users and sends out outgoing messages. This uses a client-server application model to send and receive messages using Simple Mail Transfer Protocol (SMTP).
Web Servers
A Web server is a system that delivers content or services to end users over the Internet. A Web server consists of a physical server, server operating system (OS) and software used to facilitate HTTP communication.
A Web server is also known as an Internet server.
