Definition:

Digital Rights Management (DRM) is a copy protection technology that is designed to restrict the illegal distribution of copyrighted music. Forms of control can include restrictions on the use of certain music players, how many times a purchased music file can be burnt to CD or the number of computers it can be transferred to.

For more information on DRM, read the DRM debate which explores in more detail about DRM technology.
