Links can be almost anything on the Internet, but are usually text or graphics. The easiest way to know if something is a link, is to move your mouse curser over the item, if the curser turns to a hand with it's index finger pointing at the object, if so, it's a link to somewhere.
If you leave your curser over the object for a moment, the alternate text will show itself.
With text, it is usually underlined. You may notice in the Browser Netscape, links will change color after they been clicked on, it's called a Visited Link, and let's you know you have been to that page.
