A CD drive is a device that reads and writes 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: CD-ROM drives, which only read data, and CD-RW drives, which can both read and write data. While their popularity has declined with the rise of digital downloads and streaming services, CD drives are still useful for accessing physical media and backing up data.
