Memory Management 6. Memory Management Devise an example with 8 physical pages and 16 virtual pages and 10 page faults / references. Show how the pages are paged in / out (make assumption on the page replacement algorithm you use). The following picture shows an example with 8 physical pages and 16 virtual pages, with 8 page faults. Note with 10 page faults asked in this question, with 10 > 8, the # of physical pages, some physical page(s) will be paged out. Virtual address space 60K-64K X 56K-60K X Virtual page 52K-56K X 48K-52K X 44K-48K 7 40K-44K X 36K-40K 5 32K-36K X 28K-32K X 24K-28K X 20K-24K 3 16K-20K 4 12K-16K 0 8K-12K 6 4K-8K 1 OK-4K 2 Physical memory address 28K-32K 24K-28K 20K-24K 16K-20K 12K-16K 8K-12K 4K-8K OK-4K Page frame
