OS Process Simulator

An operating system simulator that demonstrates the execution of three concurrent processes using C for backend logic and ReactJS for the frontend interface.

Features

• 🔧 Multiple Scheduling Algorithms
  Supports:

  • FIFO (First In, First Out)
  • Round Robin (RR)
  • Multi-Level Feedback Queue (MLFQ)

• ⏱️ Simulation Modes

  • Step-by-step process execution
  • Continuous (automated) simulation

• 🔒 Mutex Locks
  Ensures synchronized access to:

  • Input and output operations
  • File read/write operations

• 🧠 Simulated Memory

  • Displays Process Control Block (PCB) content
  • Mimics memory allocation and process states

• 📄 Custom Process Code Parser

  • Parses and executes specially formatted text files for each process

• 🌐 Custom Backend API

  • Backend built in C
  • Exposes APIs for frontend to control and monitor simulation

Tech Stack

• Frontend: ReactJS
• Backend: C + ExpressJS
• Communication: Custom API over REST
