"A web service is a service offered by an electronic device to another electronic device, communicating with each other via the World Wide Web. In a web service, the Web technology such as HTTP—originally designed for human-to-machine communication—is utilized for machine-to-machine communication, more specifically for transferring machine-readable file formats such as XML and JSON." -- [Wikipedia](https://en.wikipedia.org/wiki/Web_service)
