In most UNIX OS's (including Linux), you need to "mount" devices before 
you can use them. This includes hard drives, optical media (e.g. 
CD-ROM's), USB drives (external hard drives, flash drives, etc.) and so 
on. Until you start installing/removing hard drives you don't need to 
worry about those, as they are mounted for you at boot time... as well 
as any other media that happen to be present (i.e. I'm guessing this is 
why you can see a disc that is in your computer at boot time).

In KDE there is usually an icon on your desktop for removable media the 
system knows about, e.g. optical drives ('cd-rom', 'dvd' or similar), 
also e.g. any flash drives your system knows about. If you right-click 
on these you should get a 'mount'/'unmount' option. You should also 
unmount devices before removing them (for optical drives you usually* 
cannot remove the disc until you unmount the drive) to ensure that all 
data has been fully written.

(* the 'eject' option does the unmount for you... and also ejects the 
disc, of course :-).)
