What is an ISO Image?
ISO image is a term commonly associated with CD and DVD burning. An ISO image (or .ISO file) is a computer file that is an exact copy of an existing file system. An ISO can contain the entire contents of a CD-ROM disc or CD medium. ISO files are typically created through a software application that will open, create, edit, and extract CD or DVD image files, then convert the extracted image to an ISO file, easily allowing users to burn an exact copy of the original onto CD or DVD.
