'''Linux''' is the common name of a [[Unix|Unix-like]] computer [[operating system]] family that uses the [[Linux kernel]]. Almost all Linux systems rely upon [[system utility|system utilities]] and [[Library (computer science)|libraries]] from the [[GNU Project]], and so Linux is sometimes referred to as '''GNU/Linux''', though people who do not use this term claim that GNU should not be mentioned, as "Linux" is the kernel, and it is technically (though the community would probably reject it) possible to create a non-GNU Linux system, thanks to various [[BSD]] projects.

Linux is commonly packaged in [[Linux distribution|distributions]] (also known as "distros"), such as [[Debian]] or [[Red Hat Enterprise Server]], or the simple-by-design [[Ubuntu]].  A distribution consists of the Linux kernel and software bundled by the provider (plus various utilities enabling the user to install and maintain those softwares), and is generally maintained by the distributor. Most distributions are free of cost, while some cost money.
 
Initially developed and used primarily by individual enthusiasts on [[personal computer|personal computers]], Linux has since gained the support of corporations such as [[IBM]], [[Sun Microsystems]], [[Hewlett-Packard]], and [[Novell, Inc.]], and has risen to prominence as an operating system for [[server (computer)|server]]s; [[Netcraft]] [http://news.netcraft.com/archives/2006/09/06/three_hosters_share_most_reliable_hoster_in_august.html reported] in September 2006 that seven of the ten most reliable [[Internet hosting]] companies run Linux on their [[web server|web servers]].
 
Linux is used in devices ranging from [[supercomputer|supercomputers]] to [[mobile phone|mobile phones]], and has a foothold in the personal computer and business desktop markets.
 
The current version of the Linux kernel is 2.6.20.4 as of March 2007. The first number refers to the kernel version. The Linux kernel has been on version 2 since 1996. The second number is called the major version number. It has been major version 6 since December 2003. The third number is the minor revision, and reflects the addition of [[driver (computing)|drivers]] or features to the kernel. It is changed much more frequently than the first two numbers. The fourth number is sometimes used in the event of bug fixes or security updates of a critical nature.
