Priveleged Instruction set-------Part 2

To distinguish between times when privileged instructions are not allowed,most computers operate in one of two modes,usually known as supervisor mode and user mode.Priveleged instructions can be used only insupervisor mode.The switch from user to supervisor mode is made automatically in any of the following circumstances.

1. A user process calls on the operating system to execute some functions requiring the use of a privileged instructions.Such a call is termed an extracode or supervisor call.

2. An interrupt occurs

3. An error condition occurs in a user process

4. An attempt is made to execute a privileged instructions while in user mode.
