Ever have any trouble finding the power button to "turn on" a computer?

Guess what? You aren’t the only one! There are just too many different manufacturers and models for any one person to really keep track of.

Once you do get the screen to light up, you’ll face another "start up" problem: How do I get my computer to "start" doing something interesting?

What you usually see first is a part of the "operating system" called the "desktop". This is where you can "start" to run useful programs – especially once you get pretty good with a mouse.
