Fedora (previously called Fedora Core) is a yum and RPM-based GNU/Linux distribution, developed by the community-supported Fedora Project and sponsored by Red Hat. It is a complete, general-purpose operating system that contains only free and w:open source software. Fedora is derived from the original Red Hat Linux distribution, and it is intended to replace the consumer distributions of Red Hat Linux aimed towards home users. Help for Fedora comes from the greater community; while Red Hat employs many of the Fedora developers, it does not provide official commercial support and services for the distribution. New releases of Fedora come out every six months.
