A hyperlink, often referred to as a link, is a reference in a digital document that allows users to easily navigate from one section of the document or webpage to another or to an entirely different document or webpage. Hyperlinks are typically highlighted or underlined text, but they can also be represented by images or buttons. When clicked or tapped, the hyperlink directs the browser to retrieve and display the linked content, which could be a webpage, a specific section within a webpage, a downloadable file, or a multimedia resource. The underlying technology that enables hyperlinks is the Hypertext Transfer Protocol (HTTP) and its secure version, HTTPS, which facilitate the linking and accessing of content across the internet. Hyperlinks are a foundational element of the World Wide Web, as they connect related information and allow users to explore topics in depth without linear restrictions, thus creating a web of interconnected resources.
