Copy protection may include measures that are not digital. Digital rights management is a more general term because it includes all sorts of management of works, including copy restrictions. The term is also often related to, and confused with, the concept of digital rights management. "Copy protection" is a misnomer for some systems, because any number of copies can be made from an original and all of these copies will work, but only in one computer, or only with one dongle, or only with another device that cannot be easily copied.
