Test: File System & Device Management- 1 - Question 1

The page replacement policy that sometimes leads to more page faults when the size of the memory is increased is

Detailed Solution for Test: File System & Device Management- 1 - Question 1

It is due to Belady’s Anomaly in which more frames may sometimes lead to more page fault.

Test: File System & Device Management- 1 - Question 2

Which of the following page replacement algorithms suffers from Belady’s anomaly?

Detailed Solution for Test: File System & Device Management- 1 - Question 2

There are two types of page replacement algorithm mainly stack based and non-stack based, it is observed that algorithms which follows the latter one suffers from Belady’s anomaly. FIFO suffers from Belady's anomaly.

Test: File System & Device Management- 1 - Question 3

Match List-I with List-ll select the correct answer using the codes given below the lists:

Detailed Solution for Test: File System & Device Management- 1 - Question 3

SCAN is a disk scheduling algorithm:

  • Batch processing can be successfully done by FIFO without starvation.
  • Round Robin work son times haring mechanism.
  • Interrupt processing (means interrupted process to be handled, last in first out). (LIFO)
Test: File System & Device Management- 1 - Question 4

Thrashing

Detailed Solution for Test: File System & Device Management- 1 - Question 4

When to increase multi-programming, a lot of processes are brought into memory. Then, what happens is, no process gets enough memory space and processor needs to keep bringing new pages into the memory to satisfy the requests. (A lot of page faults occurs). This process of excessive page replacements is called thrashing, which in turn reduces the overall performance.

Test: File System & Device Management- 1 - Question 5

The data block of a very large file in the Unix file system are allocated using

Detailed Solution for Test: File System & Device Management- 1 - Question 5

Data block of a very large file in the UNIX file system are allocated using an extersion of induced allocation.

Test: File System & Device Management- 1 - Question 6

Given reference to the following page by a program:
0, 9, 0, 1,8, 1,8, 7, 8, 7, 1,2, 8, 2, 7, 8, 2, 3, 8, 3 
If the program contains 3 page frames.
How many page fault will occur in optimal page replacement policy?

Detailed Solution for Test: File System & Device Management- 1 - Question 6

Test: File System & Device Management- 1 - Question 7

On a system the average process size be 128 KB and each page entry requires 8 bytes then what will be the optimal page size.

Detailed Solution for Test: File System & Device Management- 1 - Question 7


Test: File System & Device Management- 1 - Question 8

How many page faults occur in LRU page replacement algorithm for the given reference

string, with four-page frames

7, 0, 1, 2, 0, 3, 4, 2, 3, 0, 3, 2, 1, 2, 0, 1

Detailed Solution for Test: File System & Device Management- 1 - Question 8

Test: File System & Device Management- 1 - Question 9

Determine the page faults when FIFO is applied to the following string with 3 frames 2, 4, 3, 1, 5, 3, 2, 5, 3, 1, 4, 2 

Detailed Solution for Test: File System & Device Management- 1 - Question 9


So, 10 page faults.

Test: File System & Device Management- 1 - Question 10

Consider the following page addresses stream frequency by executing the program with 3 frames. 1 2 3 1 2 5 8 7
By using optimal page replacement, number of page fault will be ....... and the number of page hit will be .......

Detailed Solution for Test: File System & Device Management- 1 - Question 10


So, 6 page faults and 2 page hit.
