Thanks Daniel Sadoc , Yes the book uses page size and frame size alternatively .So they are actually the same . But I don't understand about the physical address . if 2 ^ 13 bits mapped onto page of 2^5 bits, Should not the physical address (13 - 5) or (13 + 5) i.e 8 or 18. Could you please explain these . By the way , thanks again for your solution .

Does anybody have the solution of the quiestion 0329 .I have a pdf file which contains only some answers and explanation . Does anybody have the answers of 70 q please send me or post here.

Hi This question is taken from the exercise of the book "OPERATION SYSTEM CONCEPTS" BY SILBERSCHATZ GALVIN chapter "Memory management" . Could someone please answer and explain this ? Operationg System : ============== Q . Consider a logical address space of eight pages of 1024 words each, maped onto a physical memory of 32 frames . a. How many bits are there in the logical address? b. HOw many bits are there in physical address ?

Which one is bigger ? 1. A B 100210 * 900021 100021 * 900210 2 .908700 * 109880 987000 * 100988 Is there any shortcut way to do this .i.e. can we tell the result without multiplying ?

Thanks all . That is very helpfull

Hi , Could you please explain what is the process/formula to find the unit digit of a^n ? Like : What is the unit digit of (743) ^38 ? What is the unit digit of (345342) ^78 ?
