An ISO image is an archive file (also known as a disk image) of an optical disc, composed of the data contents of every written sector of an optical disc, including the optical disc file system. ISO images can be created from optical discs or from a collection of files by image creation software; images can be used to write optical discs. Software distributed on bootable discs is often available for download in ISO image format, and used to write a CD or DVD. ISO image files often have a file extension of .iso. The name ISO is taken from the ISO 9660 file system used with CD-ROM media, but what is known as an ISO image might also contain a UDF (ISO/IEC 13346) file system or a DVD or Blu-ray Disc (BD) image.
Famous quotes containing the word image:
“Not for nothing does it say in the Commandments ‘Thou shalt not make unto thee any image’ ... Every image is a sin.... When you love someone you leave every possibility open to them, and in spite of all the memories of the past you are ready to be surprised, again and again surprised, at how different they are, how various, not a finished image.”
—Max Frisch (1911–1991)
