Assignment Help:

Explain how protection is provided for the hardware resources by the operating system.

Dual mode operation

  • Sharing system resources needs operating system to make sure that an incorrect program cannot cause other programs to implement incorrectly.
  • Give hardware support to differentiate among at least two modes of operations.

1.  User mode - Implementation done on behalf of a user.

2. Monitor mode (also kernel mode or system mode) - Implementation done on behalf of operating system.
