Answer:
Intertext is putting a text in relation to another text, usually through direct quotes or references. A book that quotes another book to compare, contrast, or expand on a point is using intertext.
Hypertext by it’s nature is purely a computer construct. It’s a way of providing clickable links to other sections of a document, or other documents on the internet. It’s the basis of what we know of as the world wide web, but it started it’s life as more basic links within a document - for example clicking on a line in the table of contents would take you to that chapter. It even pre-dates WYSIWIG and mouse driven interfaces..
