A capability assigned to accounts, groups, or users allowing unrestricted memory access, access to privileged CPU instructions, and the ability to call privileged procedures.
The processor execution mode in which the kernel runs and privileged instructions (such as altering a control register) can be executed. Also called the kernel mode.
The term applied to privilege level 0. This privilege level should be used only by a protected-mode operating system. Special privileged instructions are enabled by . 286P, . 386P, and . 486P. Privileged mode should not be confused with protected mode.
