Virtual Memory Simulator

📌 Overview

This project is a Unity-based simulation program that demonstrates the concepts of Page Replacement Algorithms:

• FIFO (First In First Out)
• LRU (Least Recently Used)
• OPT (Optimal Replacement)

---

🎮 How to Play

• Select the number of page frames and reference string length at the start.
• Press the Generate Button.
• Press the Simulate Button.
• Choose an algorithm (FIFO, LRU, or OPT) to simulate.
• View the number of page faults and simulation details!

🧠 Algorithms Implemented

✅ FIFO (First-In, First-Out)

Replaces the oldest page in memory.

✅ LRU (Least Recently Used)

Replaces the page that has not been used for the longest time.

✅ OPT (Optimal)

Replaces the page that will not be used for the longest time in the future.
