Assignment Help:

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.
