DRM may refer to any of the following:
1. Short for digital rights management, DRM is a technology designed to help protect copyrighted material from being used, read, or shared without the proper rights. DRM is often achieved through a digital watermark or encryption. Although many believe DRM is the solution to protecting copyrighted material on computers, others also believe it is restrictive. For instance, DRM may prevent users from doing such things as making backups or other copies for personal use.
Music, software, and other products that have no DRM may be advertised as DRM free.
What is AODRM?
Short for always-on digital rights management, AODRM is DRM that requires the user remain connected to the Internet while playing a game or using software. If the Internet gets disconnected while the program is in use, it closes or gives an error.
2. Short for device relationship management, DRM is software that enables monitoring, managing, maintaining, and servicing devices over the Internet. These devices include any machine, instrument, or other equipment with built-in computing capability. DRM is quite useful because it allows an organization or individual to update and share information between other people and remote devices all over the world.
3. Short for Direct Rendering Manager, DRM is part of the Linux kernel that allows user programs to interface with GPU (graphics processing unit) hardware through an exposed API (application programming interface).
