Calculate physical address using the following segment offset pairs. (1
mark each)
1. 00EA:02A4=01144=1144
2. 0100:AA23=0BA23=BA23
3. D3B8:F222=E2DA2=2DA2
4. 00A0:1234=01C34=1C34
5.8FEf:0FFF=90EEF=0EEF
Detail of Solution:
Segments really describe section of 16 addresses. To get a physical address, you start with a segment, left shift once to indicate that it describes a "segment" of 16 addresses, then add the offset to get the true address.
To Confirm using Calculator, Use Scientific Calculator and Use Hexa Base Mode and Add the given offset pair .Please attacch extra 0 at the end of First offset and extra 0 at the start of second offset. as given below.
00EA:02A4 = 00EA|0+0|02A4 =1144
To confirm this Please Watch Lecture No. 4 at timing 35 minute.
