Can I use dd to create an image of a cdrom? Would that image be an iso file? Because I wanted to back up a cd, and was wondering if I could simply use dd if=/dev/cdrom of=~/cdrom.iso, and than burn it with any program.. cdrecord dev=/dev/hdd speed=4 cdrom.iso (yes, I'm using kernel 2.6.0... cool, huh?)

From an existing cd/dvd, dd will work.

In theory it will work, but if you're backing up something important you might want to burn and rip a CD, just to ensure you get the same md5sum from the original and the copy. It wouldn't be fun to find out your backup is bad.

Yes, dd works fine for that. Been using it for years.

Any general purpose distro comes with it. It's part of the GNU coreutils. "man dd" for futher info
