Web Application (a.k.a Web Service)

A web application is a computer program than runs on a remote computer and displays results in a web browser. The web application program runs on the server and the web browser provides the user with a means of controlling the data and viewing the server's information.

The single biggest advantage a web application has over run of the mill programs that run on a desktop (local) computer is the ability to update and maintain the software without having to redistribute and re-install the software whenever it is changed.

A web application can also be referred to as a web service.
