If so, then you might benefit from a quick introduction to the new computer language, Java, and some of its applications to derivatives. Let me elaborate in my own words, briefly.
Simplicity is relative and subjective.
A pplets can sit anywhere on the Internet. You grab them when you need them. This is tricky. In order to put Java source code to work, you must compile it at what we'll call level 1. You don't have to worry so much that an applet will give your computer a virus, because Java's design makes it difficult for the applet to write to the usual vulnerable places on your computer.
