Web Services..

Please excuse me for this trivial question, but I am very new to Web Services
and asp.net..

 I know that webservice is a middle appliaction which communicates with the web
server and client and hides all the low level plumbing..

But where does this webservice run?

On the client side?? Or on the server??

The code runs on the server. What runs on the client is a proxy class. If you
want to find out more about how to build a web service in C# or VB check out the
webcast: Link

The webservice would run on a computer that has direct access to the database. 
That would be on the server side, as you would not want to give client machines
direct access to the database. :)

Ok, got it..

But my next question is we add a web reference and create a proxy class and then
call the webmethod from the client..

How does the web service maintain communication with the web server??

Do we have to pass the url of the web server to the web service to
communicate??

Or any other method??

a web service is a web api that can be accesed over a network or the internet
and executed on a remote system. 

here is a presentation about web services.

the only thing you need to tell the web service is what data to return to the
application calling it.
