33. The advantage of using segment registers in 8086 and above microprocessors are that they
    

1. 1. allow the memory capacity to be 1 megabyte even though the addresses associated with the individual instructions are only 16 bits wide

   
   
   

   2. allow the instruction, data or stack portion of a program to be more than 64K bytes long by using more than one code, data or stack segment

   
   
   

   3. facilitate the use of separate memory area for a program, its data and the stack

   
   
   

   4. all of these
