Please provide corret answer and explan, thanks.

Incorrect Question 5 0/6.25 pts Numerical answer. Pay attention to questions looking similar. The virtual memory (space) of a process P contains 10 pages. The system, using Demand Paging, allocates ten frames to Process P. We assume that Process P does not waste memory. Process P generated 1000 page memory references What is the page fault rate? (Answer 1.0 if it cannot be determined with the information provided) 1.0000

Answer 1

With the given information page fault rate cannot be determined therfore answer is 1.

The correct answer for above question is 1.

Explanation:

Page Fault : it is the page replacement in virtual page memory.

Page reference is the queue of the pages required for processing.

In given question virtual page memory is 10

and Page refernce given are 1000

with out knowing the details of pages in virtual memory and the pages in reference page fault rate can not be calculated but range of fault rate can be calculated

There are chances of 100% page faults if all the 1000 page refferences are unique

There are chance of 0% of page faults if 1000 page reference has only 10 pages which are present in virtual memory.

Therefore with the given data it is not possible to calculated the page fault rate
