موفقين ان شاء الله يا طلاب
بالنسبة لأجوبة التعاليل فهب كالاتي:
1-why we put return address on stack instead of register?
because we nead the return address many time so we need multiple register .then we put it on thestack with parameter and local variable to used them later
2-whay we use privlege?
iwe use previlge if we do not need the uer programmer to modify the the programm and give power to opearating system to do this task
3-why transfer the instruction by block between memory and cach rather than word ?
beacause we need reduse the access of memory and give better performans and the block contain hole instrction if we need later
