I am confused with some concepts of assembly language. That is

How do we calculate effective address and physical address? Also differentiate them.
What is effective address generated by following instructions?
Initially
BX=0x100, num1=0x1001, =0x0000, and SI=0x0100

a. mov ax,
b. mov ax,
c. mov ax,
d. mov ax,

Calculate physical memory address generated by following segment-offset pairs.
a. 1DDD:0436
b. 1234:7920
c. 74F0:2123
d. 0000:6727
e. AB01:FFFF

Please check these and make correction to wrong calculations.

1234:7920= (1234 x 10) + 7920
= 12340 + 7920
=19C601

74F0:2123=(74F0x10)+2123
=74F00+2123
=77023


0000:6727=(0000x10)+6727
=00000+6727
=06727
AB01:FFFF=(AB01x10)+FFFF
=AB010+FFFF
=A1B00F

I really donít know how to calculate effective address. Plase explain it with some examples. Then I will try to solve my own questions.

Have you searched for its definition?
