disk image
noun
: a compressed copy of the contents (such as installed programs, settings, and other data) of an optical disc, hard drive, or other digital storage device
By developing and using a standard disk image, information technology managers don't have to separately install all of a PC's programs. The disk image is copied onto each new PC's disk drive, and it's ready to go.—
