A software program called a web service enables computer-to-computer communication over the internet. However, web services are nothing new and typically take the form of an application programming interface (API). The Web is a collection of related hypertext materials that may be accessed online. For example, a user examines web pages that may contain multimedia using a web browser and uses hyperlinks to move between them.
Tim Berners-Lee, who was employed by CERN, The European Organization for Nuclear Research, in Geneva, Switzerland, invented the Web in 1989. Since then, Berners-Lee has actively directed the development of web standards and has pushed for the creation of the Semantic Web, also called Web3.
