A DVD drive is a device that reads and writes data on DVDs, which are optical discs used for storing video, audio, and other digital information. These drives can be found in computers, gaming consoles, and standalone players. They use a laser to read the data encoded on the disc's surface, allowing users to watch movies, install software, or back up files. There are two main types of DVD drives: internal and external. Internal drives are built into the computer, while external drives connect via USB. Many DVD drives are also compatible with CDs and Blu-ray discs, providing versatility for different media formats.
