What is the full form of a CD?

The full form of CD is the Compact Disc. It has a 4.75-inch diameter, is flat, and has a small, spherical shape that can hold up to 700 megabytes of data. Since it is little, you can bring it everywhere. We may use it innumerable times because its consistency does not deteriorate over time or a lengthy period. Any digital material can be stored on CDs, including audio, video, text, photos, and more. Tiny notches on the disc store the data, which is then read by a laser from an optical drive when the disc is played.
