Live file systems can have a variety of purposes.
When you boot to a live CD/DVD/USB, system files and everything else are stored temporarily in RAM, and RAM is always cleared when a system shuts down or reboots. With a live file system, changes you make normally aren’t saved after a reboot. This is called a “live file system” and it allows you to boot into Linux like normal from a CD, DVD, or USB drive. For some Linux distros, this is actually their main purpose. Many Linux distributions offer an environment that you can boot your computer into without having to install anything to a hard drive. Furthermore, you’ll be given the information you need to make a decision about which one to use, as well as the links to the official Linux downloads pages for each Linux distribution.
In this article, we’ll cover and compare some of the most popular Linux distributions to use for a live CD/DVD.
