The main difference between a CD and a DVD lies in storage capacity and purpose: a CD is designed for audio and has a small storage capacity (approximately 700 MB), while a DVD is specifically developed for video and data and offers significantly more space (at least 4.7 GB).

The main differences:
Storage capacity: A CD typically offers 700 megabytes (MB) of space, which is equivalent to about 80 minutes of music. A standard DVD can store 4.7 gigabytes (GB) of data, which is enough for about 2 hours of video in standard resolution. Double-sided DVDs with even more capacity also exist.

Reading technique: Both discs read data using a laser. Because the pits on a DVD are much smaller and more densely packed, a more accurate laser (often red light) is required than with older CD technology.
Usage: CDs are primarily used for music albums. DVDs are universal storage media primarily used for movies, software, or large backups. Compatibility: A DVD player can usually read CDs. A standard CD player cannot read DVDs, simply because it does not have the finer laser required for the DVD structure.
