Centos 4.1 -desktop

CentOS is a freely available Linux distribution which is based on Red Hat's commercial Red Hat Enterprise Linux product, and which aims to be 100% compatible with same.

Red Hat Enterprise Linux is composed entirely of free and open source software, but is made available in a usable, binary form (such as on CD-ROM or DVD-ROM) only to paid subscribers. As required, Red Hat releases all source code for the product publicly under the terms of the GNU General Public License and other licenses. CentOS developers use that source code to create a final product which is very similar to Red Hat Enterprise Linux and freely available for download and use by the public, but not maintained or supported by Red Hat. Several other distributions have a similar origin.

See GNU or GNU General Public License for more information on copyright issues related to Linux products.
