The term "Web service" describes a standardized way of integrating Web-based applications using the XML, SOAP, WSDL and UDDI open standards over an Internet Protocol backbone. XML is the data format used to contain the data and provide metadata around it, SOAP is used to transfer the data, WSDL is used for describing the services available and UDDI lists what services are available.
A Web service is a method of communication between two electronic devices over a network. It is a software function provided at a network address over the Web with the service always-on as in the concept of utility computing.
In a Web service a Web technology such as HTTP is used for transferring machine-readable file formats such as XML and JSON.
The term Web service (WS) is either:
a service offered by an electronic device to another electronic device, communicating with each other via the World Wide Web, or
a server running on a computer device, listening for requests at a particular port over a network, serving web documents (HTML, JSON, XML, images).
In practice, a web service commonly provides an object-oriented Web-based interface to a database server, utilized for example by another Web server, or by a mobile app, that provides a user interface to the end-user. Many organizations that provide data in formatted HTML pages will also provide that data on their server as XML or JSON, often through a Web service to allow syndication.
