A
Page replacement algorithm
B
Segmentation
C
Paging
D
Segmentation with paging
Puzzles Questions answers

Question 1 Explanation: 
Page replacement is a typical online problem from the competitive analysis. They determine which pages to page out or write to disk.

Question 2
Which of the following is the simplest page replacement algorithm?
A
FIFO
B
Optimal page replacement
C
LRU replacement
D
Counting based replacement
ICT Questions answers

Question 2 Explanation: 
FIFO is the simplest page replacement algorithm since LRU and optimal replacement algorithms require past and future data patterns respectively.

Question 3
..... algorithm associates with each page the time when the page was brought into memory.
A
Optimal page replacement
B
FIFO
C
LRU replacement algorithm
D
Counting based replacement
Library science Questions answers

Question 3 Explanation: 
FIFO algorithm associates with each page the time when the page was brought into memory. The new page is inserted at the tail of the queue.

Question 4
As the number of frames available increases, the number of page faults decreases.
A
True
B
False
ICT Questions answers

Question 4 Explanation: 
One of the rules of the page replacement algorithm is that, as the number of frames available increases, the number of page faults decreases.

A
LRU replacement algorithm
B
Optimal page replacement algorithm
C
FIFO
D
Counting based replacement
Puzzles Questions answers
