Optical computing or photonic computing uses light waves produced by lasers or incoherent sources for data processing, data storage or data communication for computing.For decades, photons have shown promise to enable a higher bandwidth than the electrons used in conventional computers (see optical fibers).
An optical disc image (or ISO image, from the ISO 9660 file system used with CD-ROM media) is a disk image that contains everything that would be written to an optical disc, disk sector by disc sector, including the optical disc file system. [3]

Stacks of compact disc jewel cases. Optical disc packaging is the packaging that accompanies CDs, DVDs, and other formats of optical discs.Most packaging is rigid or semi-rigid and designed to protect the media from scratches and other types of exposure damage.
As a consequence of rapid development of electronic computers, capability for integration of existing input, output, and storage devices was a determinant factor in their adoption. [8]
A burnt Sony DVD holding a pirated copy of The Simpsons Movie. To burn an optical disc, one usually first creates an optical disc image with a full file system, of a type designed for the optical disc, in temporary storage such as a file in another file system on a disk drive.
