Hypertext refers to text displayed on a computer or website that contains links to other textual materials, often indicated with underlined blue words. When clicked, these hyperlinks take the reader to the referenced text. Hypermedia expands on this concept by linking various media types like images, sound, and video together. Multimedia combines multiple media types such as text, images, sound, and video into an integrated product or presentation in a non-linear fashion.

HYPERTEXT, HYPERMEDIA AND MULTIMEDIA
It refers to links among textual items, often indicated on a
computer or website by key words set in underlined blue
type, that, when highlighted by a pointer device and
selected or clicked, take the reader to the referent.
They are called hotlinks, hyperlinks or links. Hypertext is
often used to link text to materials traditionally contained
in footnotes and annotations but may also include much
more. Bolder explains hypertext as: ¨Electronic text is the
first text in which elements of meaning, of structure and of
visual display are fundamentally unstable¨
Hypermedia
It refers to similar links to those used in hypertext, but
instead of simply linking text to text, hypermedia involves
linking various media, such as sound, images, animation
and/or video. For example: a word or picture might have a
link to a sound file giving its pronunciation.
Multimedia
It tends to feature several media types including text,
images, sound, video, and/or animations. The term
multimedia is used to encompass the non-linear
organization of text in hypertext and the non-linear and
multiple information formats referred to in hypermedia.
