A Web service is a method of communication between two electronic devices over the Web (Internet).
• *The W3C defines a "Web service" as "a software system designed to support interoperable machine-to-machine interaction over a network".
• *It has an interface described in a machine-processable format (specifically Web Services Description Language, known by the acronym WSDL).
• *Other systems interact with the Web service in a manner prescribed by its description using SOAP messages, typically conveyed using HTTP with an XML serialization in conjunction with other Web-related standards." (Wikipedia Reference)
