A CD/DVD drive is a hardware component in computers and some other devices that allows users to read and write data on CDs (Compact Discs) and DVDs (Digital Versatile Discs). These drives can play music, movies, and software stored on these discs, making them useful for entertainment and data storage. Most modern computers come with either internal or external CD/DVD drives. While many users have shifted to digital downloads and streaming, these drives are still valuable for accessing physical media, backing up data, and using older software that may be available only on discs.
