1. 1. If DS = 7FA2H and the offset is 438E,
   (a) Calculate the physical address
   (b) Calculate the lower range
   (c) Calculate the upper range of the data segment
   (d) Show the logical address
   2. If SS = 3500H and the SP is FFFEH,
   (a) Calculate the physical address of the current top of the stack,
   (b) Calculate the lower range.
   (c) Calculate the upper range of the stack segment.
   (d) Show the logical address of the stack.
   (e) What is the range of physical addresses if CS = FF59 ?
   3. If the current value of the stack segment register and stack pointer are C00016 and F F0016, respectively, what is the address of the current top of the stack ?
   4. For the base and offset addresses in previous problem, how many words of data are currently held
   in the stack ?
   5. Show how the value EE1116 from register AX would be pushed onto the top of the stack as it exists
   in previous problem.
   6. Assume that the DS register is 578CH. To access a given byte of data at physical memory location
   67F66H. Does the data segment cover the range where the data is located ? If not what changes need
   to be made ?
