    Answer 1.
    The value of the stack segment register (SS) = 7698h
    The value of the stack pointer (SP) which is Offset = 01FFh
    Thus, Physical address of the top of the stack is:

    7 6 9 8 0
    + 0 1 F F
    7 6 B 7 F

    This calculation can be expressed as: Physical address = SS (hex) x 16 + SP (hex).
    Answer 2.
    The value of the code segment register (CS) = 5526h
    The value of the Instruction Pointer, holding address of the instruction = 8874h
    Physical address of the instruction
    Physical Address = CS (Hex) x 16 + IP

    5 5 2 6 0
    + 8 8 7 4
