Compact discs (CDs) store information in discreet steps. Information is stored on a CD in the form of a series of pits and lands on the surface of the disc, which are read by a laser beam. The laser scans the disc, and the light is reflected off the pits and lands to create a digital signal that is then converted into analog sound. Each pit and land represents a binary digit, allowing for precise storage and retrieval of information.
