Digital Rights Management (DRM) refers to technologies and code used to protect copyrighted digital content from unauthorized access, copying, or distribution. DRM is often added to digital media like software, e-books, music, and video to control how consumers can use that content.

Some examples of what DRM can do when implemented in code include:

• Restricting the number of devices that can access the content.
• Limiting the number of times content can be shared or downloaded.
• Blocking unauthorized copying or modifying of content.
• Enforcing expiration dates or rental periods for accessing content.

The goal of DRM is to prevent piracy and protect intellectual property, but it has also sparked debates about the balance between consumer rights and copyright protection.
