Page replacement algorithms are essential in operating systems, particularly in managing main memory efficiently.
As systems encounter memory shortages, these algorithms play a vital role in deciding which pages should be swapped out from memory (page eviction) to accommodate new ones (page allocation).
Visualizing these algorithms provides a clearer understanding of their functionality and performance. This web page serves as a visual aid to comprehend and compare popular page replacement algorithms , namely:

  • First-In-First-Out (FIFO)
  • Second Chance (SC)
  • Least Recently Used (LRU)
  • Optimal (OPT)
Through interactive Chart.js visualizations, this webpage illustrates the number of page faults incurred by each algorithm under various scenarios. Users can explore and compare the efficiency of these algorithms in managing memory resources, gaining insights into their strengths and limitations.
