Consider a demand-paging system with the following time-measured utilizations: CPU utilization 20% Paging disk 97.7% Other I/O d

Zarrin [17]

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

(Optional.)

h. Increase the page size. Answer:NO

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

kompoz [17]

Answer: False

Explanation:

Certification in Audio Engineering equips one with skills needed in the music industry such as being able to record, mix and master sounds as well as knowledge of studio equipment such as microphones, speakers, consoles and the computer software needed to blend all these components together.

As such, it can take a bit of time to learn it adequately enough to be certified. This is why Technical colleges offer certifications in audio engineering through programs that usually last between 6 months and a year.
