1. In 8086 complete 1MB memory is divided into 16 logical segments.
2.Each segment thus contains 64 KB of memory.
3. While addressing any location in the memory bank, the Physical address is calculated from two parts, the first part is Segment address, and the second is Offset.
4.The segment registers contain 16-bit segment base addresses related to different segments.
5.Thus the CS, DS, ES, SS segment registers, respectively contain the segment addresses for the Code, Data, Extra and Stack segments.
6. They may or may not be physical separated.
7.Each segment register contains a 16-bit base address that points to the lowest-addressed byte of that particular segment in memory.
