DVD

A DVD (Digital Versatile Disc) is a type of optical storage medium used to store digital data, such as movies, music, or computer files. It uses laser technology to read data stored on its surface, which is encoded in tiny pits on a reflective layer. DVDs can hold significantly more information than a CD, typically up to 8.5 GB on a dual-layer disc. They are commonly used for watching movies on DVD players or storing backups. DVDs are portable, durable, and easy to use, making them a popular choice for distributing multimedia content.
