We've covered a lot of ground here, but we are by no means finished. Those things we attach to our PCs aren't much good if we don't put them in context with the tools we use them for. Those tools tend to require a somewhat more in-depth examination. For instance, burning CDs isn't just about creating collections of your favorite songs. People use them for backups as well, or to make collections of digital photos for sharing with the family.
The same is true of scanners. These gizmos are incredibly handy devices for the home or office. Aside from converting nondigital pictures to place on your Web site, you can use your scanner as a photocopier and as a way to send faxes when the pages require your signature (you can fax from a word processor, after all).
We cover all those things in the chapters to come.
