DRM

Short for Digital Rights Management, DRM is a name for a collection of technologies that aim at preventing digital media from being copied. DRM takes many shapes, for instance in early computer games, some games would use a form of DRM to prevent piracy by requiring users to answer specific questions out of the supplied manual. During the era when CDROMs contained more space than comparable hard drives (mid-to-early 90s) some games would fill up the entire space of a CDROM with junk data, to prevent the game from being copied and run from a user's local hard drive.

Modern DRM protects more than simply computer games, extending to all forms of digital media including movies, music, ebooks and software. While DRM attempts to prevent widespread piracy, often times hackers can circumvent DRM and pirate the media regardless, rendering DRM efforts most restrictive to average, every day users. Users typically run into problems with DRM when attempting to backup, transfer or otherwise move media from one computer to another, or one device to another.
