OS- Page Replacement Algorithm Simulator

The goal of the Page Replacement Algorithm Simulator project was to provide a platform to simulate and compare various page replacement algorithms like FIFO, LRU, MRU, OPR using Python and Tkinter

The project was aimed at providing an easy-to-use Graphical User Interface (GUI) application that can be used by students, researchers, and professionals to study and compare the performance of different page replacement algorithms.

Features of the project

The Page Replacement Algorithm Simulator project comes with several features that make it a useful tool for studying and comparing different page replacement algorithms. Some of the important features of the project are:

• User-friendly Interface
• Multiple Algorithms: 1.FIFO (First In First Out)
  2. LRU (Least Recently Used)
  3. OPR (Optimal Page Replacement) 4. MRU (Most Recently Used)
• Real-time Simulation
• Interactive Bar Charts
• File handling as it saves results to a file : page_replacement_results.txt.
