The Fedora project is the upstream, community distro of Red Hat® Enterprise Linux.

Can I use Fedora to learn Red Hat?

Absolutely. These days, RHEL (and indirectly, CentOS) derives almost directly from Fedora, so learning Fedora will help give you an edge in future technologies in RHEL. Honestly, learning ANY Linux will teach you your way around ANY UNIX operating system, to a first approximation.

What is the Red Hat called?

Red Hat got its name from founder Marc Ewing who wore a red Cornell University lacrosse hat, given to him by his grandfather, while attending Carnegie Mellon University.
