CD stands for Compact Disc, an optical medium that can
store digital data. This was the medium that was created to
replace the old cassette tapes. A standard CD can hold
700MB of data, around 80minutes of CD quality audio, or up
to 60minutes of video. The later standard called the
Digital Versatile Disc or DVD is still an optical media
much like the CD but with much greater capacities, starting
at 4.7GB at the low end to as high as 17GB. The high
capacities allow DVDs to contain so much more information,
aside from the songs and movies, compared to CDs
