Question $1$:

For the following Assembly language instructions:

MOV AX$,$ OABCDH

MOV $[2000],$ AX

MOV AX$,5678H$

MOV BX$,[2000]$

HLT

Show the contents of the $Ax$ register, $Bx$ register, and the memory locations $2000$ and $2001.$

Question $2$:

Which of the following statements give an error when written in the EMU$8086$ and which are accepted. If the statement gives an error state the reason.

$-$ MOV $AL,1234h$

$-$ MOV $AX,1234H$

$-$ MOV $SI,1234h$

$-$ MOV $[AX],1234H$

$-$ MOV $[SI],1234h$

$-$ MOV $[SI],AX$

Question $3$:

Write an assembly code that initializes the Registers AX$,$ BX$,$ and $Cx$ with the values $1234,5678,$ and ABCD respectively then exchange their values using the Stack so that the final values for them are $Ax=5678,Bx=$ABCD, and $Cx=1234.$

Question $4$:

Write an assembly code that triggers both the Parity and the Sign flags at the same time. $($i$.$e changes the parity flag from $0$ to $1$ and the sign flag from $0$ to $1).$

Question $5$:

Show the content of the AX and BX registers after executing each line of the following code.

MOV AL$,10$

MOV BL$,0$AH

XOR AL$,$ BL

NOT AX

AND AL$,5$H

OR AX$,$ BX
