Page "Applet" Paragraph 4

An applet can also be a text area only, providing, for instance, a cross platform command-line interface to some remote system.

If needed, an applet can leave the dedicated area and run as a separate window.

However, applets have very little control over web page content outside the applet dedicated area, so they are less useful for improving the site appearance in general ( while applets like news tickers or WYSIWYG editors are also known ).

Applets can also play media in formats that are not natively supported by the browser
