One of the ways in
which Web pages have become more dynamic is through their support of executable
content, such as Java applets and ActiveX controls. These page elements are downloaded
to the browser and run in its memory space to produce dynamic content on the browser
screen. For placing executable content in web page, HTML uses <APPLET>
tag (for Java applets), <OBJECT> tag (for other executable objects) and
<PARAM> tag (for passing parameters to applet and object tags).
