A data CD is a compact disk formatted to store files. The types of files typically stored on a data CD might include compressed zip files, word processing documents, spreadsheets, text files, graphics, QuickTime-style movie files, or MP3 music files.

A Data DVD is not a movie. DVD is storage medium just like a CD that requires a DVD drive in your computer. It can hold any kind of data, including digitized movies but it is not exclusive to movies. It can be used to hold audio, video, computer files, and/or digital photos. The most important difference between a DVD and a CD is the amount of data it can hold. While a CD can hold 650MB of data, a DVD can hold 4.7GB of data or nearly 7 times as much.

What is Audio CD?

The logical format of an audio CD (officially Compact Disc Digital Audio or CD-DA) is described in a document produced by the format's joint creators, Sony and Philips in 1980. The document is known colloquially as the "Red Book" after the color of its cover. The format is a two-channel 16-bit PCM encoding at a 44.1 kHz sampling rate per channel. Four-channel sound is an allowable option within the Red Book format, but has never been implemented. Monaural audio has no existing standard on a Red Book CD; mono-source material is usually presented as two identical channels on a "stereo" track.

What is ISO image?

An ISO image is an archive file (also known as a disc image) of an optical disc in a format defined by the International Organization for Standardization (ISO). This format is supported by many software vendors. ISO image files typically have a file extension of .iso. The name ISO is taken from the ISO 9660 file system used with CD-ROM media, but an ISO image can also contain a UDF file system since UDF is backward-compatible with ISO 9660.

What is CD-RW?

CD-RW (for compact disc, rewriteable) is a compact disc (CD) format that allows repeated recording on a disc. The CD-RW format was introduced by Hewlett-Packard, Mitsubishi, Philips, Ricoh, and Sony, in a 1997 supplement to Philips and Sony's Orange Book. CD-RW is Orange Book III (CD-MO was I, while CD-R was II). Prior to the release of the Orange Book, CDs had been read-only audio (CD-Digital Audio, described fully in the Red Book), to be played in CD players, and multimedia (CD-ROM), to be played in computers' CD-ROM drives. After the Orange Book, any user with a CD Recorder drive could create their own CDs from their desktop computers. CD-RW drives can write both CD-R and CD-RW discs and can read any type of CD. The ideal usage field of CD-RW is in the creation of test disks, temporary short or mid-term backups, and in general, where an intermediate solution between online and offline storage schemes is required.
