What does a Compact Disc (CD) primarily store?

A Compact Disc (CD) primarily stores data, which can include music, video, graphics, and other forms of digital information. The most common use of CD technology has been for audio recordings, enabling users to listen to music on CD players. However, CDs can also store various types of data through the method of burning data onto the disc, making them versatile for different applications.

The ability to store both data and music highlights the flexible nature of CDs, as they were designed to hold digital information in a format that can be read by compatible devices. While you could store graphics, software applications, and text documents on a CD, the essential characteristic that distinguishes it is its dual capability for both audio and general data storage.
