Consider a computer with the following properties: 32-bit addresses, byte addressing 256-byte pages A page table entry occupies 4 bytes The machine can use 1-level page tables, or 3-level paging (with 8 address bits devoted to each level). a. For 1-level paging, if all addresses are in use, how many page tables are needed and how much memory is occupied by page tables? b. For 3-level paging, if all addresses are in use, how many page tables are needed and how much memory is occupied by page tables at each level? c. For 1-level paging, if only the lowest 4, 096 and highest 4, 096 addresses are in use, how many page tables are needed and how much memory is occupied by page tables? (Recall that 4, 096 equals 2^12) d. For 3-level paging, if only the lowest 4, 096 and highest 4, 096 addresses are in use, how many page tables are needed and how much memory is occupied by page tables at each level? e. Discuss the relative advantages and disadvantages of 1-level paging and 3-level paging, assuming all addresses are used. f. Discuss the relative advantages and disadvantages of 1-level paging and 3-level paging, assuming only the lowest 4, 096 and highest 4, 096 addresses are used
