Servers

Servers often provide essential services across a network,
either to private users inside a large organization or to
public users via the Internet. Typical computing servers
are database server, file server, mail server, print server,
web server, gaming server, and application server.[2]
Numerous systems use this client server networking
model including Web sites and email services. An alternative
model, peer-to-peer networking enables all computers
to act as either a server or client as needed.

 

A server is a running instance of an application
(software) capable of accepting requests from the client
and giving responses accordingly. Servers can run on any
computer including dedicated computers, which individually
are also often referred to as “the server”.
Servers operate within a client-server architecture.
Servers are computer programs running to serve the requests
of other programs, the clients. Thus, the server
performs some tasks on behalf of clients. It facilitates
the clients to share data, information or any hardware
and software resources. The clients typically connect to
the server through the network but may run on the same
computer. In the context of Internet Protocol (IP) networking,
a server is a program that operates as a socket
listener.
