Answer #1

As we see from the illustration, physical address 1650 lies in the segment that resides at addresses 1504 - 1791 in memory.

Note that 1504 is the base-address of this segment, and 1791 is the end-address of this segment.

As seen from the illustration, the segment between 1504 - 1791 has segment-number 4.

Also, the segment-offset for 1650 is given by

= (physical address) - (base address of segment)

= 1650 - 1504

= 146

So the answer is

(4,146)
