Detailed explanation-1: -Web services are XML-based information exchange systems that use the Internet for direct application-to-application interaction. These systems can include programs, objects, messages, or documents. A web service is a collection of open protocols and standards used for exchanging data between applications or systems.

Detailed explanation-2: -The aim of the Web Service protocols is to provide a means of describing data and behavior in a machine-processable way. Web Services use XML to describe metadata for discovery purposes and to define behaviour, and in general presume that XML documents will be the payload of the messages exchanged.

Detailed explanation-3: -One of the primary advantages of the XML Web services architecture is that it allows programs written in different languages on different platforms to communicate with each other in a standards-based way.

Detailed explanation-4: -Web services are self-contained, self-describing modular applications that can be published, located, and invoked across the Web. Web services are self-contained. On the client side, no additional software is required. A programming language with XML and HTTP client support is enough to get you started.
