basically registers are used to store data and address. for
specifying the base address i.e starting block of
memory ,segment registers are used . it gives only the
starting adress of any segment .one thing is important in
the case of 8086 architechture is that ,for producing
physical address ,the segment register address must be
rotate bit-wise 4 times left and 0000 must be embedded. now
offset address is added in the modify content of segment
register to get the required memory location.
