Window based displays like this one are becoming common on home
computers, so you may have seen a similar system before. If you
are used to MacOS or MS Windows, you already know some of the basics.
The approach is similar in X Windows, but not as uniform.
A lot of the power in using X Windows comes from the underlying
operating system, Unix, since it allows you
to run several tasks at a time. It's a lot easier to keep track of
several tasks if each one has its own window.
