An ISO file is an "image" of what should be on a CD or DVD disc. The ISO file itself is generally useless until it can be written or burned to a disc. The CD/DVD burning software you already have on your computer probably has a "write image" or "burn image" option designed specifically for writing ISO and other types of image files to CD or DVD discs.
