Included with this book is a full-featured Linux distribution that runs entirely from the CD-ROM. The WFTL Edition Knoppix CD is a Debian-based Linux distribution that runs entirely from your PC's CD-ROM drive. That's right. You can run Linux on your system without having to change your system or uninstall Windows.
Running WFTL Knoppix is as easy as putting the CD in the drive and booting. A couple of minutes later, you are working with a great-looking, modern desktop (Figure 2-1). This CD is full of excellent software. There are hundreds of applications and literally thousands of programs on the disk. You'll have access to e-mail applications, Web browsers, word processors, spreadsheets, games, and more. In fact, you should be able to follow along and play with the software you'll explore in this book and do most of the things that are covered without having to install Linux at all.

The bootable CD is a fantastic introduction to Linux, providing you with a no-commitment way to take Linux out for a spin, but there are limitations. I've already covered one issue related to CDs, that of performance. The other limitation is also CD related. Because this bootable Linux does not install itself on your hard drive, you are limited to the packages on the CD. In other words, you can't add or install any new software. If you are truly ready to make the move to Linux, consider installing a full Linux distribution.
