c. Berners-Lee also wrote communication protocols such as JavaScript Object Notation (JSON) to form the backbone of his new hypertext information system, which he referred to as the World Wide Web.
d. In 1994, Berners-Lee founded the World Wide Web Consortium (W3C), devoted to developing web technologies.
Answer: c. Actually, in 1989, Tim Berners-Lee of CERN (the European Organization for Nuclear Research) began developing HyperText Markup Language (HTML)—the technology for sharing information via “hyperlinked” text documents.
1.11 Q4: Which of the following statements about the cloud is false?
a. A service that provides access to itself over the Internet is known as a web service.
