What is an image?
An image is a direct representation of a CD, DVD, hard drive or another storage medium. The
difference from a copy or backup is that an image contains information about the structure of the original
storage medium, and not just individual files. This enables 1:1 copies of complete storage media to be
created.
Some file extensions of images are: iso, img, nrg.
Images can also be mounted as a virtual drive. All of the data on the medium can be made accessible
without having to copy all of the data to the PC or having to insert the disc into the drive.
ISO image
is the name of an image on a CD/DVD in the ISO 9660 format. This norm indicates that the file system
was copied without any changes, so that the files can be exchanged between different operating systems
like Microsoft and Apple.
