WEB Service vs ???

A WEB service runs on a server, and clients consume the service, correct?  What alternatives are there to a WEB service, if i need to have a server/host take send/receive data from clients?  Is a WEB service cross-platform? Microsoft only?

I would like to focus a bit more on the last part of your question:
Is a WEB service cross-platform? Microsoft only?
A Web Service is nothing more than an endpoint on a server that receives a request and replies to it.
As the web uses the HTTP, a web service is known for using this transport protocol to operate.

With this said, the technology you use to develop such a service is an implementation detail.

Web Services are often divided into two main categories: SOAP and REST but the same web service can be configured in a way that supports both.
Again, the technology used is a mere implementation detail.

You'll find that most web technologies have a way to implement web services and depending on that, you need to choose the server technology that supports that implementation.
For instance, if you choose to go on the Microsoft WCF path, you'll need to have an IIS to host it.
On the other hand, if you're more of a JAVA guy, maybe you might need to use a JBOSS or something else.
These are just two examples, but there are plenty other alternatives.

Wcf and mvc you can use to compare
All three are cross domain and should not have any isssues

Let's simplify things for a minute.  Web servers accept requests and reply with responses using the HTTP protocol.  They were originally intended to serve web pages to web browsers.  However, anything that can be fit into that protocol can be done with clients and web servers.  I use custom client programs to download CSV files.

There is software that is called Web Services.  Although they aren't necessarily all the same, they will each have specific requirements for requests and responses.  What ever you do, the requests and the responses should be well defined so the system works well.

Where could I find a list of server technologies that supports implementation?  What the most used technology?  Are there advantages and disadvantages of the various technologies ?

Basically all web servers (IIS, Apache, nginx, and others) support 'web services'.  The web services are 'supplied' by software that is running on the web servers.  That can be almost anything that a client can request and get a response from the server.

That is almost like what kind of web page can I get.  The possibilities are huge.  To get a more useful answer, you need to narrow down what you want to do.
