Hypertext is a system for managing information non-sequentially by linking documents together. It allows users to easily follow cross-references between documents. Hypertext has advantages like easy retrieval of information through global views and references. However, it can also cause users to feel disoriented with many interconnected nodes. Hypertext applications include product catalogs, manuals, dictionaries, and educational resources. It can be used in education by implementing hyperlinks between texts and media for language learning skills like reading, writing, listening and speaking.
