Solution
a.Indicate the physical memory location corresponding to
logicaladdress 8050.
The logical address 8050 is 50 more than 8000. Thus the
physical memory is 50 greater than physical address
30300 which is 30350
Indicate the logical address corresponding to physical
memory location 23123.
The physical address 23123 is 1123 more than 22000.
Thus the logical address is 1123 greater than logical
location 6000 which is 7123
