Browsers provide a graphical interface to information on the Web. They display pages written in HTML and make it possible for you to click on links to jump to other pages. This neat invention is called hypertext.
The most popular browsers are Microsoft Internet Explorer (IE) and Mozilla Firefox. Regardless of which browser you choose, you can access the same information and can configure the software to match your personal preferences.
Each browser interprets some HTML elements in its own way, so the same page might display differently, depending on which browser you use.
