Answer:

see explaination please

Explanation:

a. Install a faster CPU. Answer:NO

Optional: a faster CPU reduces the CPU utilizationfurther since the CPU will spend more time waiting for a process toenter in the ready queue.

b. Install a bigger paging disk. Answer:NO

Optional: the size of the paging disk does not affect theamount of memory that is needed to reduce the pagefaults.

c. Increase the degree of multiprogramming Answer:NO

Since each process would have fewer frames available andthe page fault rate would increase

d. Decrease the degree of multiprogramming.Answer: YES

Optional: by suspending some of the processes, the otherprocesses will have more frames in order to bring their pages inthem, hence reducing the page faults.

e. Install more main memory. Answer:Likely

Optional: more pages can remain resident and do notrequire paging to or from the disks.

f. Install a faster hard disk or multiplecontrollers with multiple hard disks. Answer:Likely

(Optional)

g. Add prepaging to the page-fetchalgorithms.Answer: Likely
