But what I don't understand is why a device would show in my /dev when there isn't even one there.  My current system looks like this...

That's because those nodes are created to deal with those devices, whether they
exist or not.

The CD-ROM drive would be /dev/hdd, if it's the slave on a secondary IDE
connection. /dev/cdrom is merely a symbolic link which points to the actual
device which refers to the cdrom (try "ls -l /dev/cdrom") - much as /dev/modem
points to the actual serial port (/dev/ttyS2, for example) which connects to a
modem.
