A CD drive is a device used to read and write data on compact discs (CDs). It allows users to access music, software, and other types of information stored on these discs. CD drives can be found in computers, laptops, and standalone players, making it easy to enjoy digital content. There are two main types of CD drives: internal and external. Internal drives are built into the computer, while external drives connect via USB. Although less common today due to the rise of digital downloads and streaming, CD drives are still useful for accessing physical media and backing up data.
