What does a hyperlink allow users to do?

A hyperlink primarily serves the function of connecting users to other web pages or resources, which involves the navigation of content. This ability to link various documents or parts of documents allows users to seamlessly explore related information, hence controlling the flow of their reading experience by guiding them to different areas of content or to entirely different websites.

While some might consider other options, they do not encapsulate the core purpose of a hyperlink. For example, changing text format is about document styling, enhancing image quality relates to visual aspects, and connecting to external applications is more aligned with API functions or software integration rather than hyperlinks specifically. The function of a hyperlink is not directly about formatting or quality enhancement; it is fundamentally about connecting and navigation.
