thanks to both of u guys.. really kind of u..
..
as u can see it's 3:30 am & i still can't sleep..
my interview in few hours..
i'm reading & trying to memorize as much as i can find from the internet..
i needed answers for those questions bcoz when i google them i get a very complicated full topics.. i just need a simple answer to show the interviewer that i know what i;m talkin about.. that's it..
i am not lazy man..
thanks any way..
