A simplified client-server solution for file management

A client-server application can be simplified to describe a model wherein a program (the server) receives and handles requests of services done by another program (the client). The server program awaits requests done by the client program and begins working on a request as soon as it is received. The two programs are often referred to as one application.

The client-server model is used all around us; websites, chat programs, and email are just a few examples.
