Consider a 32-bit OS that runs on a machine with 64MB of physical memory. The OS divides the 32-bit logical address space into pages. Each page is sized of 4KB. There are 4 methods for translating a virtual address to a physical address: (a) one-level page table (b) two-level page table (the first level page table has 256 entries; we only need the first level page table and first one of the second level page table to be saved in memory) (c) hashed paged table (the range of the value returned by the hash function is between 0 and 27) (d) inverted page table. Please calculate the memory space required for a process's page table in each method under the assumption that each entry in the page table is sized of 4 bytes
