Hypertext
A hypertext is a text that is organized like a network. Parts of the text reference other text messages or texts which can directly be accessed. The parts that provide the reference are known as hyperlinks. An example of a hypertext is the HTML standard used in the World Wide Web. Wikis also use hypertext.
