Question: Assume Processor registers with initial values ( prior to execution of any instruction below ) . A x = A 5 B 6 ; B

Assume Processor registers with initial values (prior to execution of any instruction below).
Ax=A5B6;Bx=4455;Cx=BA8E;Dx=3CB6;SS=179D;DS=179D
If the stack was initially empty, and the instruction "Push CX" was executed then mention
the byte locations, in logical and physical addresses, where the low byte (BL) and high
byte (HL) of the register CX are stored on the stack.
Now assume a new stack with SP=013C;SS=179D. How many valid bytes of the stack
are shown in the memory dump above?
How many invalid bytes are shown in the memory dump above that are not part of the
stack mentioned in question 2?
Shown the contents (in Hex) of the word on the top of the stack mentioned in question 2.
Shown how the contents (in Hex) of the memory dump above changes when two
instructions - Push BX and Push CX - are executed.
Shown the final value of SP and SS after the two "Push" instructions are executed in
question 5.
Show further changes in the contents of the memory dump after the following 4 additional
instructions are executed:
a) Pop AX;
b) Add CX, AX;
c) MovBx,Cx;
d) Push BX
Assume Processor registers with initial values (
