1. Define addressing mode? 2. Define immediate addressing mode and give two examples using the \( \mathrm{CX} \) and \( \mathrm{AH} \) register? 3. Define register addressing mode and give two examples using the \( \mathrm{AL}, \mathrm{BH}, \mathrm{BX} \) and \( \mathrm{DX} \) registers? 4. Define direct addressing mode and give two examples using \( \mathrm{AH} \) and \( \mathrm{CX} \) registers? 5. Define register indirect addressing mode and give two examples using the following registers \( \mathrm{BX}, \mathrm{DI}, \mathrm{AX} \) and \( \mathrm{AL} \) ? 6. Give the addressing mode of the following: A) MOV AX, 0234 B) MOV \( [\mathrm{BX}], \mathrm{AH} \) C) MOV DX, BX D) MOQ [0200], BL 7. What is an offset register? 8. Which register is the offset register of \( \mathrm{CS} \) ? If \( \mathrm{CS}=1635 \) and \( \mathrm{IP}=0100 \), what is the physical address? 9. Which registers are the offset registers of DS? If \( D S=3510 \) and SI \( =0205 \), what is the physical address of the memory? 10. What are the values in the \( \mathrm{AX}, \mathrm{BX} \), and \( \mathrm{CX} \) registers after executing this program? MOV AX, \( 4142_{16} \) MOV BX, \( 2020_{16} \) MOV CX, \( 1010_{16} \) ADD AX, BX SUB BX, CX INT 03 11. What is the machine code of the above program? 12. Use the register-addressing mode and write a program to copy register \( \mathrm{AX}=4545 \) into \( \mathrm{BX} \) and \( \mathrm{BX} \) into \( \mathrm{CX} \) (program from step 5 above)?
