Most people's computers come with many hardware items already installed on them. With prices coming down like they have been, it is not unusual any more for a person who is new to computers to also own a scanner or digital camera -  maybe you fall into this category.

Using a cd-rom isn't difficult, but maybe you would like to shut off auto-run, and don't know how. Printers also are not difficult to run, but have you ever run into a printing problem that the help files didn't address? 

Scanners are the latest computer peripheral to drop greatly in price, but if you've just bought one, you may not have any idea of how to set it up or use it. Do you know how important the resolution is when scanning? What is color balance and how do you get rid of red-eye?

Cameras, too, are dropping in price, and since you can download pictures directly from the camera to your email, it helps to have the abilities to know how to use these tools to the utmost!
