Java Animations

On this page you find several applets simulating aspects of the lectures Computer Networks and Multimedia Technology of the Department of Applied Computer Science IV in the University of Mannheim. All these applets have been developed by students. We would be happy to hear your feedback for these applets. Please contact liebig@pi4.informatik.uni-mannheim.de with any comments.
This site uses JavaTM technology. If you encounter any problems displaying the java applets please check the external java.com test page. Want to learn more about JavaTM? Here is an external link to some additional information.
