Browsers provide a graphical interface to information on the Web. They display pages written in Hypertext Markup Language, or HTML. Hypertext is the neat invention that makes it possible for you to click on links to jump to other pages.

Some of the most popular browsers are Microsoft's Internet Explorer (IE) on Windows computers, Firefox on Windows and Macintosh computers, and Safari on Macintosh computers. Regardless of which browser you choose, you can access the same information.

Each browser interprets some HTML elements in its own way, so the same page might display differently, depending on which browser you use.
