Is there a difference between a web server and a web service?

terminology

Solution

A web service is an application that is run by a web server and that results in a series of URLs that will return their data in a format that is intended to be parsed by a 'generic' computer program instead of by a browser. As a result web services can use any data format they want (as long as both sides agree), but typically something like XML (specifically SOAP or so) or JSON is used.
