Linux (, LIN -uuks )[ 15] is a family of open-source Unix-like operating systems based on the Linux kernel ,[ 16] an operating system kernel first released on September 17, 1991, by Linus Torvalds .[ 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]
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 .[ 21] [ 22] Thousands of distributions exist, many based directly or indirectly on other distributions;[ 23] [ 24] popular Linux distributions[ 25] [ 26] [ 27] 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.[ 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 for smartphones , they have the largest installed base of all general-purpose operating systems .

The shared commonality of the kernel is what defines a system's membership in the Linux family; the differing OSS applications that can interact with the common kernel are what differentiate Linux distributions.
