Answer:
Check the explanation
Explanation:
For 9th byte , it is from 8*8 bit to 9"8th bit so each word consists of 64 bits , to find word address u have to divide 8*8 by 64.
Offset within word = 9*8modulo 64.
For 27th byte , word address = 8*27/64.
Offset within word = 27* 8 modulo 64
For 21th byte , word address = 8*31/64
Offset within the word = 31*8 modulo 64
For 120 , word address = 8*120/64
Offset within the word = 120*8 modulo 64.
