Final answer:
Hyperlinks are used to provide additional information on a topic by redirecting users to different resources, such as academic materials, videos, or interactive sites.
Step-by-step explanation:
Hyperlinks are used to provide additional information about a topic by taking the user someplace else. These links can be found throughout digital texts and offer a convenient way for readers to access additional content without cluttering the main body of the text. For example, sidebar links might connect to academic materials, You-Tube for video content, or interactive mapping and data sites. Annotated bibliographies also use hyperlinks to connect to more details about each source, and in a glossary, hyperlinked terms provide direct access to definitions and related terms. The capability to navigate back from such linked resources is a significant convenience, enabling users to explore without losing their place in the original document.
