A server is a computer or device on a network that manages network resources. Servers are often dedicated and they perform only their server tasks.
Strictly speaking, the server is the software that handles a certain task. However, the powerful hardware that supports this software is also usually called a server because server software coordinating a network of hundreds or thousands of clients requires hardware much more robust than what you'd buy for ordinary consumer use.
