Suppose that a machine has 42-bit virtual addresses and 32-bit physical addresses. a. How much RAM can the machine support (each byte of RAM must be addressable)? b. What is the largest virtual address space that can be supported for a process? c. If pages are 2 KB, how many entries must be in a single-level page table? d. If pages are 2 KB and we have a two-level page table where the first level is indexed by 15 bits, then how many entries does the first-level page table have? e. With the same setup as part {d}, how many entries are in each second-level page table? f. What is the advantage of using a two-level page table over single-level page table?
