In the world of (which runs on an Linux kernel), a rooted device is one where OS protections have been disabled, allowing processes to run as root, and thus do things they would normally be prevented from doing, such as reading all files on the device.

Not to be confused with CERN's ROOT framework for statistical analysis in C++, see .
