World Wide Web (also called WWW or W3) is an information system based on hypertext, which offers a means of moving from document to document (usually called to navigate) within a network of information.
Hypertext documents are linked to each other through a selected set of words. For example, when a new word, or a new concept, is introduced in a text, hypertext makes it possible to point to another document which gives more details about it. The reader can open the second document by selecting the unknown word or concept and the relevant section is displayed. The second document may also contain links to further details. The reader need not know where the referenced document is, and there is no need to type a command to display it, or to browse it to find the right paragraph. Cross-references may be defined in the same document. A collection of documents is a database.
