Would some one describe the offset and base location in detail. To me segment is the memory chunk, base location is the starting address of the memory chunk and offsets is the displacement from the base to the end of the chunk.
If possible provide some links also.

Thanks!

Real-address mode, in

<segment value>:<offset> 

physical address= segment value * 16 + offset

One thing to understand about segmented addressing is that there are many different segment/offset combinations that can access one memory address. For example, segment 0x0000 offset 0x0010 is the same as segment 0x0001 offset 0x0000. The question I can't answer is WHY it works like this :P
