Hyperlinks are the key component of HTML which enables webpages to link to other webpage and thus creating the metaphorcal "web" of links.

The Internet is the network infrastructure of global interconnected networks utilising the TCP/IP protocol. The World Wide Web of which hyperlinks play a key part is an application that operates over the Internet.

A hyperlink (often referred to as simply a link), is a reference or navigation element in a document to another section of the same document, another document, or a specified section of another document, that automatically brings the referred information to the user when the navigation element is selected by the user. As such it is similar to a citation in literature, but with the distinction of automatic instant access. Combined with a data network and suitable access protocol, a computer can be instructed to fetch the resource referenced.

Hyperlinks are part of the foundation of the World Wide Web created by Tim Berners-Lee, but are not limited to HTML or the web. Hyperlinks may be used in almost any electronic media.
