Question
Suppose we have a 64-bit system that uses 4KB pages. The highest 7 bits of each virtual address are not used. Suppose the PTE of the top-level table at index 0 has 0 as the contents of the address field. This fact means that approximately how many bytes of memory are unallocated? Use a decimal approximation based on the rule, 210 - 103 256 quadrillion O 64 quadrillion 256 trillion. O 64 billion
