What is dvd meaning?

DVD stands for Digital Versatile Disc. It is a digital optical disc storage format that was invented in the late 1990s. DVDs come in two sizes, 4.7 gigabytes (GB) and 8.5 GB. The discs can be used to store various types of digital data, such as movies, music, photos, and software. DVDs have replaced the VHS tape as the dominant format for video home entertainment. They are played back using a DVD player, which reads the information encoded on the disc's surface. DVDs are widely used for both commercial and personal use, and they can be burned or copied to create backups or duplicates.
