In banking, CD also means certificate of deposit, a savings product where you deposit money for a fixed term to earn interest. A more general sense you might see is as a shorthand in informal writing for compact disc. The concept is memorable: a small, hand-sized disc that can hold hours of music or important data, depending on the context.
