I think this is applicable to dos progams. In *nix and windows systems, it doesn't make sense. NEAR pointers are the normal pointers we use which can access upto max of 65,535 bytes using the 16 bit registers. FAR and HUGE ptrs allows us to access memory higher than 65,535 by using two registers (one for offset and other for segment). FAR pts are used in non-normalized mode (like TSR progs) where as HUGE ptrs are normalized (normal progs).
