WiKi百科对Hypertext的解释

Hypertext is text displayed on a computer display or other electronic devices with references (hyperlinks) to other text that the reader can immediately access, or where text can be revealed progressively at multiple levels of detail (also called StretchText). Hypertext documents are interconnected by hyperlinks, which are typically activated by a mouse click, keypress sequence or by touching the screen. Apart from text, the term "hypertext" is also sometimes used to describe tables, images, and other presentational content forms with integrated hyperlinks. Hypertext is one of the key underlying concepts of the World Wide Web, where Web pages are often written in the Hypertext Markup Language (HTML). As implemented on the Web, hypertext enables the easy-to-use publication of information over the Internet.

Hypertext,超文本,它是文本,包含了Hyperlinks(超链接)的文本。简单说,Hypertext就是包含了Hyperlink的文本,或者说hypertext通过Hyperlinks相互连接。HTML就是Hypertext Markup Language的缩写。

 

WiKi百科对Hypermedia的解释

Hypermedia, an extension of the term hypertext, is a nonlinear medium of information that includes graphics, audio, video, plain text and hyperlinks. This designation contrasts with the broader term multimedia, which may include non-interactive linear presentations as well as hypermedia. It is also related to the field of electronic literature. The term was first used in a 1965 article written by Ted Nelson. The WWW (World Wide-web) is a classic example of hypermedia, whereas a non-interactive cinema presentation is an example of standard multimedia due to the absence of hyperlinks.

Hypermedia,超媒体,是Hypertext的扩展,非线性媒体信息,包含了图片,语音,视频,文本,超链接等各种元素。超媒体与多媒体对应。

互联网就是超媒体的典型案例。

应为缺少超链接,电影这样的展现就是典型的多媒体的案例。

 

按照这两者的含义来看,HTML的H,其实就是Hypermedia的含义。
