Calculate physical address of the following segment offset pairs. Explain each and every step for calculating the physical address.                                                                        

1. 2C3E:0199
2. 8000:0250

Solution:
Segment Address = Segment Register x 10.
Offset Address = Logical Address.
Physical Address = Segment address + Offset Address
 1.      2C3E:0199
Segment Address = 2C3E x 10 = 2C3E0.
Offset Address = 00199.
Physical Address = 2C3E0 + 00199 = 2C579.
 2.      8000:0250
Segment Address = 8000 x 10 = 80000.
Offset Address = 0250.

Physical Address = 80000 + 00250 = 80250.
