What Are the Different Kinds of Servers?
A server is a device (most likely a computer) on a network that manages resources that multiple people access daily. These resources can include applications, databases, files, websites and other resources. Servers are often more powerful than regular computers in order to support fast peripheral devices and large storage capacities. There are several types of servers that may be used in an office, school or home.

Proxy Server
-
A proxy server is an application or computer system that acts as an intermediate between two computers: one that is seeking data or resources and one that is providing the information. The first computer connects to the proxy and requests access to files, connections, Web pages, applications or other resources. The proxy, using filter technology such as an IP address or protocol, validates the request. The proxy then sends the data from the source to the computer that is asking for the resources. Most proxy servers are related to connecting a computer to the Internet.
Printer Server
-
A printer server consists of a computer or device that is connected to several printers and other computers within a network. The printer server accepts requests to print from other computers in the network and sends those requests to the correct printer. This allows computers that aren't physically connected to a printer to wirelessly print jobs. Modern print servers can connect multiple printers to a Local Area Network (LAN) or Wi-Fi to allow remote computers to connect using a wireless router.

Mail Server
-
Mail servers are used by businesses to regulate email sent to workers. A mail server acts as an outbound client and an inbound retrieval server, commonly using the simple mail transfer protocol (STMP). When an email address on the server receives an email from another server, the two mail servers interact with each other. The inbound mail server will filter the email to make sure that its content is suitable for delivery.
Media Server
-
Media servers are used to stream audio and video on computers using an Internet connection. The servers allow media-centric businesses to transfer files that have a high bandwidth. Most media servers have a hardware configuration with multiple-core processing power and high quantities of random access memory (RAM). Servers often host their audio and video in a cluster of Web proxy servers. Therefore, when you receive the audio or video, you often receive multiple streams of the same content.
