A DVD player is an electronic device that plays discs containing movies, shows, or other video content. It reads the data stored on DVDs and converts it into a format that can be displayed on a TV. Many DVD players also support other formats, such as CDs for music and Blu-ray discs for high-definition video. Most DVD players come with a remote control, making it easy to navigate through menus and select what to watch. Some models even offer additional features like USB ports for playing files from flash drives or Wi-Fi connectivity for streaming content online.
