A server is a computer, a device or a program that is dedicated to managing network resources. Servers are often referred to as dedicated because they carry out hardly any other tasks apart from their server tasks.
There are a number of categories of servers, including print servers, file servers, network servers and database servers.
In theory, whenever computers share resources with client machines they are considered servers.
