Linux is an open source operating system (OS) that is lightweight and runs on many systems. It also runs on the Arduino Yún. There are different "flavors" or "distros" (distributions and changes made by different groups) of Linux such as Ubuntu, Debian, and Fedora. All versions of Linux use the Linux Kernel as the base of the OS. The kernel was released in late 1991.
