The objective is to simulate virtual memory paging and evaluate the performance of different page replacement algorithms using reference strings. Simulate virtual memory paging for a specific reference string and analyzing the performance of various page replacement algorithms. The goal is to compare the page fault rates generated by different algorithms, including Belady's Optimal algorithm. Task 1: Page Replacement Algorithms Implement the following page replacement algorithms: FIFO (First-In-First-Out): Implement the FIFO page replacement algorithm. LRU (Least Recently Used): Implement the LRU page replacement algorithm. Random: Implement a random page replacement algorithm. This means that you will replace a random page. Belady's Optimal: Implement Belady's Optimal page replacement algorithm. This requires you to look ahead in the reference string and find which of the pages that you have currently in frames will go the longest without reference. Task 2: Simulation Simulate the execution of each of the implemented page replacement algorithms using the same reference string. The reference string represents memory page references made by a process over time. Your program should prompt for the number of frames and the reference string. Task 3: Performance Evaluation For each page replacement algorithm, run the simulation and calculate the following: Page Fault Rate: Calculate the page fault rate for each algorithm. The page fault rate is the percentage of memory accesses that result in page faults. Comparison: Compare the page fault rates obtained for each algorithm and analyze their performance.

The objective is to simulate virtual memory paging and evaluate the performance of different page replacement algorithms using reference strings. Simulate virtual memory paging for a specific reference string and analyzing the performance of various page replacement algorithms. The goal is to compare the page fault rates generated by different algorithms, including Belady's Optimal algorithm.

Task 1: Page Replacement Algorithms

Implement the following page replacement algorithms:

FIFO (First-In-First-Out): Implement the FIFO page replacement algorithm.
LRU (Least Recently Used): Implement the LRU page replacement algorithm.
Random: Implement a random page replacement algorithm. This means that you will replace a random page.
Belady's Optimal: Implement Belady's Optimal page replacement algorithm. This requires you to look ahead in the reference string and find which of the pages that you have currently in frames will go the longest without reference.

Task 2: Simulation

Simulate the execution of each of the implemented page replacement algorithms using the same reference string. The reference string represents memory page references made by a process over time.

Your program should prompt for the number of frames and the reference string.

Task 3: Performance Evaluation

For each page replacement algorithm, run the simulation and calculate the following:

Page Fault Rate: Calculate the page fault rate for each algorithm. The page fault rate is the percentage of memory accesses that result in page faults.

Comparison: Compare the page fault rates obtained for each algorithm and analyze their performance.
