What is a hyperlink?
A hyperlink (or just link) is a piece of text or image on a website that connects (or links) you to another page or file on the internet. Hyperlinks are conventionally distinguished from their context with an underline and/or a different color.
How does a hyperlink work?
Hyperlink derives its name from HyperText, the HT in HTTP. At its core, hypertext is text that references other text. The text that is linked is called “anchor text.”
Hyperlinks aren’t just used by humans. Web crawlers, such as the ones used by Google to index web pages, can follow hyperlinks to retrieve their documents and files.
