This document discusses hypertext and its applications, including in education and language learning. Hypertext is defined as a non-linear system for managing information that allows users to easily follow cross-references. It enables a more flexible structure than traditional text by incorporating links between nodes of information, which can include text, graphics, sounds or other media. The document outlines some advantages of hypertext, such as easy creation of references and global views of information, but also notes it can make information more difficult to obtain as networks grow larger. Applications mentioned include product catalogs, reports, contracts, resumes and more. The document also discusses how hypertext can be used to support all language skills in educational settings.
