A program written in a portable, platform-independent computer language, such as Java, JavaScript or Visual Basic (An applet is usually embedded in an HyperText Markup Language (HTML) page downloaded from web servers and then executed by a browser on client machines to run any web-based application (e.g., generate web page input forms, run audio/video programs, etc.). Applets can only perform a restricted set of operations, thus preventing, or at least minimizing, the possible security compromise of the host computers. However, applets expose the user's machine to risk if not properly controlled by the browser, which should not allow an applet to access a machine's information without prior authorization of the user) |
