Red Hat vs. Fedora

[Nathan England]

All,

Possibly a dumb question, so I apologize ahead of time!

I Know admittedly little about Red Hat or Fedora.
If I decided I want to learn as much about Red Hat as possible, should I 
get an official Red Hat release or is Fedora similar enough that I could 
learn how Red Hat does things? Is there enough difference that I would 
have a problem going back and forth between desktops with Fedora and 
servers with Red hat?
