how do you determine the reverse mask and which bitwise to use like OR or AND? Explain in detail please how to get the answer.

The IP address of a computer is 155.90.75.64/21. The network address of the subnetwork that this computer belongs to is 155.90.72.0/21 Binary Values of the network address: 155=1001101190=0101101072=Youcalculate0-Youcalculate What is the broadcast address of the network this computer belongs to? Note: write full address that you calculated in DDN format. HINT: This is like the address calculation questions I provided in the exercises. You would NOT the SNM and XOR that value against the network address binary value. When entering your answer in the provided blank, enter the address you have calculated in the same format as I used for the IP address of the computer
