By now you should be quite adept at creating Web pages with HTML. You've probably also spent a fair amount of time surfing the Web, and you should now know how to recreate many of the things you've seen there. But you've probably also run across pages that have used some tools and techniques that we haven't discussed yet. So you're probably wondering "What else can I add to my Web pages?"

Two of the ways Web pages are frequently "enhanced" is to go beyond HTML by using CGI scripts and Java applets. While some enhancements of a Web page can be achieved with either of these, one or the other may be better suited in some cases, and there is a fundamental difference in the way they work. We'll consider this difference as we look at these two approaches in greater detail.
