(a) Describe what virtual memory is and explain its impact on multiprogramming (b) Describe what hierarchical (a.k.a. multilevel) and inverted page tables are and explain their advantages over a single-level page table. (c) Assume that a computer uses 32-bit virtual addresses, byte-level addressing and 4KB pages i. Determine the maximum size of the virtual address space per process. ii. Compute the number of entries in the single-level page table. iii. Describe an architecture for a two-level page table for this computer.
