HotJava removes the static limitations of the Mosaic generation of Web browsers with its ability to add arbitrary behavior to the browser. Using HotJava, you can add applications that range from interactive science experiments in educational material, to games and specialized shopping applications. You can implement interactive advertising, customized newspapers, and a host of application areas that haven't even been thought of yet. The capabilities of a Web browser whose behavior can be dynamically updated are open-ended. Furthermore, HotJava provides the means for users to access these applications in a new way.
Software migrates transparently across the network as it's needed.
This transparent acquiring of applications frees content developers from the boundaries of the fixed media types such as images and text and lets them do whatever they'd like. The central difference between HotJava and other browsers is that while these other browsers have knowledge of the Internet protocols hard-wired into them, HotJava understands essentially none of them. What it does understand is how to find out about things it doesn't understand. The result of this lack of understanding is great flexibility and the ability to add new capabilities very easily. Dynamic Content One of the most visible uses of HotJava's ability to dynamically add to its capabilities is something we call dynamic content.
