Which of the following best defines the World Wide Web?

The World Wide Web is best defined as an information service that connects documents via hypertext links. This definition captures the core functionality of the Web, which allows users to access a vast network of information from different sources seamlessly. It is the system that enables documents hosted on various servers around the world to interconnect through hyperlinks, making it easy for users to navigate from one piece of content to another.

The hypertext feature is fundamental to how the Web operates, as it allows for the inclusion of links within a document that direct users to other related documents, whether they are located on the same site or elsewhere on the internet. This interconnectedness and the ability to easily navigate and retrieve information is what distinguishes the World Wide Web from merely being a network of computers or a searching software program. It also sets it apart from methods of web hosting, which simply refer to the practices of storing and serving web pages rather than the functionality of linking and accessing a vast array of information.
