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 data stored on these discs. CD drives can be found in computers, laptops, and standalone players, making it easy to enjoy audio or install programs. 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 digital downloads and streaming, CD drives remain useful for accessing physical media and backing up data.
