the power of definition

Have you ever got a simple question from a non-techie person, like "What is Java"?

Here is a portion of what you get from wikipedia on Java:

Java refers to a number of computer software products and specifications from Sun Microsystems that together provide a system for developing application software and deploying it in a cross-platform environment

Here is what you'd enjoy from its official site:

Java allows you to play online games, chat with people around the world, calculate your mortgage interest, and view images in 3D, just to name a few.

That really makes my day.
