Digital rights management, or DRM, is a way to control digital things.

It uses tools to manage how people use files. These files might be music, movies, or software.

One way DRM works is through encryption. Encryption is a way to scramble information. Only people with a special key can unscramble it. This helps owners protect their work. It is like a digital lock. Some companies use DRM to allow rentals. This lets people pay to use a file for a short time.

DRM can also be used on hardware. This means physical machines. Some coffee makers and light bulbs use it. Even some tractors use DRM. This can make it hard for farmers to fix their machines.

Many people find DRM to be a problem. It can make it hard to make backup copies. It can also stop people from borrowing books from a library. If a service stops working, the files might stay locked forever. Some people protest these digital locks.
