A hyperlink, also known as link or web link, is an icon, graphic, or text within a document that you can click on to jump to a new document or object. They are often blue and underlined and whenever you move the cursor over them the arrow changes to a small hand pointing at the link.
Bearing the above in mind it could be said that, " a <em>hyperlink</em> provides direct access from one document or Web page to another"
