A- Consider a computer system that provides a virtual memory space that consists of 8 pages. The physical memory contains 4 pages where the page size is 4Kbytes. Assume that at specific moment, the physical page frames (0-3) were holding the following pages in order: 5, 2, 4 and 7. Then answer the following questions:
1- Draw the overall memory structure including: virtual memory, physical memory, disk system, and the page table.
2- Show the mapping process from virtual pages to the physical page frames as well as the content of page table and the disk system.
3- Give the format of both the virtual and the physical memory addresses.
4- If a user process generates the following virtual addresses, find out the corresponding physical address.
