[ 17 ] [ 18 ] [ 19 ] Linux is typically packaged as a Linux distribution (distro), which includes the kernel and supporting system software and libraries —most of which are provided by third parties—to create a complete operating system, designed as a clone of Unix and released under the copyleft GPL license. [ 20 ] Thousands of Linux distributions exist, many based directly or indirectly on other distributions; [ 21 ] [ 22 ] popular Linux distributions [ 23 ] [ 24 ] [ 25 ] include Debian , Fedora Linux , Linux Mint , Arch Linux , and Ubuntu , while commercial distributions include Red Hat Enterprise Linux , SUSE Linux Enterprise , and ChromeOS . Linux distributions are frequently used in server platforms. [ 26 ] [ 27 ] Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses and recommends the name "GNU/Linux" to emphasize the use and importance of GNU software in many distributions, causing some controversy . [ 28 ] [ 29 ] Other than the Linux kernel, key components that make up a distribution may include a display server (windowing system) , a package manager , a bootloader and a Unix shell . Linux is one of the most prominent examples of free and open-source software collaboration. While originally developed for x86 based personal computers , it has since been ported to more platforms than any other operating system, [ 30 ] and is used on a wide variety of devices including PCs, workstations , mainframes and embedded systems . Linux is the predominant operating system for servers and is also used on all of the world's 500 fastest supercomputers . [ g ] When combined with Android , which is Linux-based and designed
