A DVD (Stands for Digital Versatile Disc)is a type of optical media used for storing digital data. It is the same size as a CD but has a larger storage capacity.
The original "DVD-Video" format was standardized in 1995 by a consortium of electronics companies, including Sony, Panasonic, Toshiba, and Philips.
It provided a number of improvements over analog VHS tapes, including higher quality video, widescreen aspect ratios, custom menus, and chapter markers, which allow you to jump to different sections within a video.
DVDs can also be watched repeatedly without reducing the quality of the video and also used to distribute software programs.
