Explanation

In Linux, the protection rings refer to different levels of privilege within the operating system. Ring 3 is the least privileged and is associated with user-level processes. These processes run with minimal privileges to prevent them from directly accessing or altering critical system resources. Rings 0 through 2 are used for kernel and higher levels of system functionality, with Ring 0 being the most privileged (kernel mode).
