if(i%j==0)
fact++;
}
if(fact==2)
printf("%d " ,i);
}
return 0;
}
Why are page sizes always powers of 2?
Answer: Paging is implemented by breaking up an address into a page and offset number. The most efficient method is to break the address into X page bits and Y offset bits. This is done rather than performing calculations on the address to calculate the page number and offset. Splitting an address between bits results in a page size that is a power of 2 because each bit position represents a power of 2
