The official Red Hat DVD (disk 1) can serve as a bootable emergency disk for most modern PCs with BIOS that can boot from DVDs.
It includes file system tools for emergency system administration. Using this disc you can attempt to recover from file system-related crashes.

The Common UNIX Printing SystemTM, or CUPS, is the software you use to print from applications like the web browser
you are using to read this page. It converts the page descriptions produced by your application into something your printer
can understand and then sends the information to the printer for printing.

Every printer manufacturer does things differently, printing can be very complicated. CUPS does its best to hide this from you
and your application so that you can concentrate on printing and less on how to print.

UUID (Universally Unique Identifier) is the only way to guarantee you recognize the same drive or partition no matter what.
If you introduce to your system another hard drive, this might upset quite a few things, starting with the way your system boots up
(or stops booting up upon the new drive introduction). Using UUID helps remedy most of such things so on.
