Protection ring: A security mechanism that divides a system into different levels of security, with each level providing different levels of access to system resources. This is commonly used in operating systems to prevent unauthorized access to sensitive data and system resources. Examples include the rings in the Intel x86 architecture and the Kernel Mode in Windows.
