What is digital versatile disc?

Answer 1

A Digital Versatile Disc (DVD) is an optical disc storage format that can hold significantly more data than a standard compact disc (CD). Introduced in the late 1990s, DVDs are commonly used for storing video, audio, and computer files, with capacities typically ranging from 4.7 GB for single-layer discs to 8.5 GB for dual-layer discs. They support a variety of formats, including DVD-Video for movies and DVD-ROM for data storage. DVDs have largely been succeeded by Blu-ray and digital streaming technologies, but they remain popular for certain applications.
