"Link" and "hyperlink" actually both refer to the same thing.

A link is a reference on a web page that references some other place on the same page or somewhere else on the Internet. If text is "clickable" that means it is a hyperlink.

You can identify a hyperlink in a number of ways but the easiest way is to move your mouse pointer over the top of a picture or word and if your mouse cursor change to look like a small hand then the item you are looking at, is a link and you can click it.
