A “web service”, is a technology that provides an interface for some functionality to make it accessible from other programs across the web. This functionality might be obtaining data from a database, performing a mathematical calculation, or enabling remote control of a device.

Dear sivak,
Read MSDN notes for Web-Service. I think MSDN documents will assist you.
