(computer science)
A method of computer operation in which the computer can execute all its own instructions, including the privileged instruction not normally allowed to the programmer, in contrast to problem mode.

supervisor mode

(Or "supervisor state") An execution mode on some processors which enables execution of all instructions, including privileged instructions. It may also give access to different a address space, to memory management hardware and to other peripherals. This is the mode in which the operating system usually runs.

Opposite: user mode.
