Explanation / Answer

a)
A segment represents an independently addressable unit ofmemory consisting of 64K consecutive byte -wide storagelocations .Each segment is assigned a base address that identifiesits starting point. Only four segments can be active at a time:
                                             The code segment                                               Thestack segment                                              Thedata segment                                             The extra segment The addresses of the active segments are storedin internal segment registers CS, DS,ES ,SS.
b)Four active memorysegments
                               Code segments-64K
                               Stack -64K
                                Datastorage -128K
c)       The dedicated memory(0001416 ~0007F16) are used foe storage ofthe data and instructions  8088's instructionsin a program
