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.
