A Server is a computer or device through which network resources are controlled. For instance, a file server is a storage device that stores files. Files can be stored on the server by any user on the network. Similarly, a print server is a computer that is used to run one or more printers and network traffic is controlled by network server.
Normally, servers do not complete any other tasks other than their own jobs. On parallel processing operating systems on the other hand, a single computer can perform more than a few applications at the same time. A server can refer to the application that is managing resources more willingly than the whole computer.
