When you click on a link, your browser brings you the linked web page.
Links can take many forms.
Linked text will often change color after you've used it, to help you remember which web pages you've already visited. Some linked graphics are outlined to show that they are links. Other linked graphics change when you move your cursor over them to show that they they are links. The only sure way to find out whether text or graphics are linked is to move your cursor over them. If your cursor changes from an arrow into a hand, it's a link.
