You can get the free operating system Linux (operating system) running on a computer system to boot Linux from a Linux installation CD (or DVD) and installing Linux. And you can also run Linux by booting a Linux system from a live CD / DVD.
Once you have Linux, you can learn to use Linux and get lots of great practical experience and training on Linux.
You can run commonly used Linux software and also work with the Linux command line and learn to use Linux commands - the way the real pros do Linux system administration.
2 Reasons to Boot Linux from CD / DVD So You Can Get Linux Training

1. Boot Linux from a Linux installation CD / DVD.

In this case, you need to boot from a Linux CD / DVD and run the Linux installation routine to install the Linux OS (operating system) on the hard disk in your computer system.

When you install Linux, the Linux OS and thousands of Linux software programs are installed on your hard disk permanently (until you decide to remove Linux or upgrade Linux).

After installing Linux, you boot Linux from the hard disk in your system. You don't need to boot Linux from a CD or DVD in your CD / DVD drive.

Linux Tips: There may be more than one Linux CD / DVD required for a Linux installation. If so, always use CD 1 (or DVD 1) to boot Linux and run the Linux installation routine.

2. Boot Linux from a Linux live CD / DVD

You boot Linux from a Linux "live" CD / DVD to run a "live" version of Linux.

When you boot and run a Linux live CD / DVD, the complete Linux OS (including Linux software programs and a Linux desktop) runs from a single Linux live CD / DVD. This is a very fast, easy, and fun way to run Linux.

Linux Tips: If you have a DVD drive, rather than a CD drive, and want to buy a Linux live CD / DVD, buy the Linux live DVD instead of a live CD. A Linux live DVD holds about six times as much as a Linux live CD and you will usually get lots more Linux software programs on the live DVD version, as opposed to the live CD version.

Linux Tips: To get a Linux live DVD, look around the Internet a bit to see if there is a DVD version for the Linux distribution (version) you want. If you can find the Linux live DVD for the Linux distro you want, pay the small difference in price to get the live DVD rather than live CD.
