1. Variable TOTAL is defined as follows: TOTAL DD 1023h, 122F5AC1h, 12E0A55 How many bytes does the variable TOTAL occupy in memory? a. 3 b. 6 c. 9 d. 12 2. Consider the following Intel 8086 instruction MOV BYTE PTR (BX], 5. The keyword "BYTE PTR" is needed to: a. Indicate that is an immediate operand b. Indicate that 5 is an indirect operand c. Indicate that 5 is an address d. Indicate that 5 is an 8-bit number 3. If we have the following assembly code: data MI db 3, 5, 7, 9, 2, 4 .code startup a. Write code to load the offset address of M1 array in BX register Mov dl, [BX] Add dl, [BX+2] Sub dl, [BX +4] Move ah, 4ch INT 21H END b. What is the value in DL after executing the mov instruction? c. What is the value in DL after executing the Add instruction? 1.
