Answer / naresh

intel 8086 processor is 16 bit processor, so segment registers are 16 bit in size,but physical address need 20 bit,in order to generate 20 bit physical address segment register is appended by zero at last bits to make it 20 bit.This append process is taken by address generation circuit inside the 8086 chip.
For example segment register value is "1600 H", it's modified by address generation circuit by appending zero at last. the value is "16000 H"

This address is added with respective offset register to know the exact position in memory.
