Answer #1
  1. Monitor mode has higher priority than User mode i.e. if while executing in User mode if an interrupt is encountered CPU switches to Monitor mode.
  2. In Monitor mode, the CPU can use all the instructions and access all the areas of the memory. On the other hand, In User mode, the CPU is restricted to unprivileged instructions and a specified area of the memory.
  3. User codes should always be executed in User mode .The CPU automatically switches to Monitor mode whenever an interrupt or trap occurs. So, OS codes are run in Monitor mode.
