For the following reference string apply the FIFO page replacement algorithm. For the following reference string...
Consider the following reference string: How many page faults would this string produce under the FIFO page replacement strategy with three frames? How many page faults would this string produce under the OPT replacement strategy with three frames? How many page faults would this string produce under the LRU replacement strategy with three frames?
Given the following page-reference string, show the allocation of 3 frames of memory using FIFO , LRU and OPT. How many page faults for FIFO, LRU and OPT? 3,1,2,1,3,1,4,1,3,2,4,2,5,6,4,6,2,1,6,5
Consider the following page reference string for a three-frame memory: 6 3 1 5 3 4 3 2 5 4 3 4 5 1 5 3 1 6 3 1 Apply LRU, Clock and FIFO algorithms What will be the number of page faults for each replacement algorithm note that page faults at the beginning are counted?
Apply the (1) FIFO, (2) LRU, and (3) optimal (OPT) replacement algorithms for the following page-reference strings: • 2, 6, 9, 2, 4, 2, 1, 7, 3, 0, 5, 2, 1, 2, 9, 5, 7, 3, 8, 5 • 0, 6, 3, 0, 2, 6, 3, 5, 2, 4, 1, 3, 0, 6, 1, 4, 2, 3, 5, 7 • 3, 1, 4, 2, 5, 4, 1, 3, 5, 2, 0, 1, 1, 0, 2, 3, 4, 5, 0, 1 • 4, 2, 1,...
1. Given a reference string generated by a process, how many page faults occur with N frames if page replacement is by LRU, or FIFO, or the optimal algorithm? please explain
find the number of page faults that occur during FIFO, OPT, LRU cafe replacement with 4 frames. Mention the number of page faults after each replacement strategy. If you find any ties replace the page with the highest numeric value. Here is the reference of string pages. 9 2 6 9 6 0 5 5 6 0 3 1 6 1 0
Write a program that implements the FIFO, Optimal, MFU, and LRU page-replacement algorithms. Given a page-reference string, where page numbers range from 0 to 9, apply the page-reference string to each algorithm, and output the number of page faults incurred by each algorithm. Write your code so that the number of page frames in the page table can vary from 1 to 10. 1.0 Functional Requirements 1.1: Your program shall be run with the following: ./a.out Example: ./a.out datafile.txt 1.2:...
Consider the following page reference string: 5, 3,7,5, 3, 6, 1, 0,4,6,2,0,1,2,7,3,1,4,7,2 Assuming demand paging with three frames, how many page faults would occur for the following replacement algorithms!? LRU replacement FIFO replacement Optimal replacement
Assume demand paging with three frames. Consider the following page reference string: 7, 2, 3, 1, 2, 5, 3, 4, 6, 7, 7, 1 If OPT replacement is used, the number of page faults will be a. 8 b. 9 c. 10 d. 7 e.None of the above If LRU replacement is used, the number of page fault will be a. 8 b. 9 c. 10 d. 11 e. None of the above
