Ring Inc hires you to design the virtual memory system for a new cell phone with 32-bit virtual and physical addresses, in which memory is allocated in 1 KB pages. Suppose that you decide to use a single-level page table, in which you also store three metadata bits for each page: Writable, Executable and Valid. [5 marks] -) Answer the following questions, briefly explaining your solution: (i) How long, in bits, is a virtual page number? (ii) How long, in bits, is a physical page number? (iii) How long, in bits, is an offset within a page? (iv) How much memory is needed to store the page table of each process?
