Answer
For First physical memory address,we add 00000 in segment values.
For Last physical memory address,we add 0FFFF in segment values.
<u>NOTE</u>-For addition of hexadecimal numbers ,you first have to convert it into binary then add them,after this convert back it in hexadecimal.
a)1000
For First physical memory address, we add 00000 in segment value
We add 0 at the least significant bit while calculating.
1000<u>0</u> +00000 = 1000<u>0</u> (from note)
For Last physical memory address,We add 0 at the least significant bit while calculating.
we add 0FFFF in segment value
1000<u>0</u> +0FFFF =1FFFF (from note)
b)0FFF
For First physical memory address,we add 00000 in segment value
We add 0 at the least significant bit while calculating.
0FFF<u>0</u> +00000=0FFF0 (from note)
For Last physical memory address,We add 0 at the least significant bit while calculating.
we add 0FFFF in segment value
0FFF<u>0</u> +0FFFF =1FFEF (from note)
c)0001
For First physical memory address,we add 00000 in segment value
We add 0 at the least significant bit while calculating.
0001<u>0</u> +00000=00010 (from note)
For Last physical memory address,We add 0 at the least significant bit while calculating.
we add 0FFFF in segment value
0001<u>0</u> +0FFFF =1000F (from note)
d) E000
For First physical memory address,we add 00000 in segment value
We add 0 at the least significant bit while calculating.
E000<u>0</u> +00000=E0000 (from note)
For Last physical memory address,We add 0 at the least significant bit while calculating.
we add 0FFFF in segment value
E000<u>0</u> +0FFFF =EFFFF (from note)
e) 1002
For First physical memory address,we add 00000 in segment value
We add 0 at the least significant bit while calculating.
1002<u>0</u> +00000=10020 (from note)
For Last physical memory address,We add 0 at the least significant bit while calculating.
we add 0FFFF in segment value
1002<u>0</u> +0FFFF =2001F (from note)
