Web Services - Interview Question PrepareVideo


Web services are software applications that communicate with each other over the internet, using several standardized technologies (collectively the Web Services Architecture, WSA ) for machine-to-machine interaction.

“A Web service is an abstract notion that must be implemented by a concrete agent. The agent is the concrete piece of software or hardware that sends and receives messages, while the service is the resource characterized by the abstract set of functionality that is provided. To illustrate this distinction, you might implement a particular
Web service using one agent one day (perhaps written in one programming language), and a different agent the next day (perhaps written in a different programming language) with the same functionality. Although the agent may have changed, the Web service remains the same.”
