Chapter 12. Executable Content > Applets and Objects

12.1. Applets and Objects

Applets, like client-side image maps, represent a shift in the basic model of web communications. Until recently, servers performed most of the computational work on the Web, client browsers being not much more than glorified terminals. With applets, web technology is shifting toward the client, distributing some or all of the computational load from the server to the client and its browser.

Applets also represent a way of extending a browser's features without forcing users to purchase or otherwise acquire a new browser, as is the case when developers implement new tag and attribute extensions to HTML. Nor do users have to acquire and install a special application, as is required for helper or plug-in applications. This means that once users have a browser that supports applets (Netscape and Internet Explorer do), you can deliver applets immediately, including display and multimedia innovations.
