Web Service is a technical entity representing and interface (logical and physical), whichhas its own description language (semantics) and programmming platform and programming language agnostic. Then interface may be mapped on different protocols and defined by different standards. The most popular Web Services are WSDL-based and REST-based. Source: CoolInterview.com

Corrections:
1) Web Service is an interface
2) Web Service is programmming platform and programming language agnostic
3)access to the interface may be mapped on different protocols and defined by different standards

As a result, the name "Web Service" is inconsistent because
a) it is not a service;
b) it may be mapped onto a communication protocol different from the one used in Web. For example, the Web Service may be accessed via messaging system or via SMTP (SIMPLE MAIL TRANSFER PROTOCOL) Source: CoolInterview.com
