    Hi and welcome, what do you mean exactly by webservices? It could be any of the following:

    Web development (programming - which then could be php, asp, and so on)
    Web hosting
    Domain registration
    DNS
    web support
    Webmarketing and SEO
    security

    and probably more...

    Hi,

    Web services are functionalities provided by applications over web. they are more enhanced than a simple web site.

    user controls- within same application
    custom controls - when strong name - can b used between different applications - they have to be installed / shared in your system using GAC.
    Web services - functionality can be used directly over web.

    its one way to implement credit card validation / credential check using other's functionality (methods)in your code directly.

    Web services are a set standards that you can implement to provide RPC style functionality. They are now under the control of W3c. It started off as SOAP (Simple Object Access Protocol) and was a reaction to earlier object remoting and distribution frameworks like CORBA / DCOM. Ironically SOAP itself is now no longer simple either. Many people are rejecting the complex set of standards in favour of REST. If you want security you may well be well served by the standards however.

    The main benefits that sold SOAP were interoperability and the ability to 'tunnel' or use port 80 and hence not be encumbered by the myriad of firewalls organisations now install.

    Many programmers however have such a poor understanding that they still struggle to write usable web services from an interoperability standpoint.

    A verbose text based wire format is also not really a great idea in general, thats why we have binary protocols.
