💻 OS Lab Programs in C | CPU Scheduling, Memory Management, IPC, Deadlocks | Well-documented & beginner-friendly

Primary LanguageC

🧪 Operating Systems Lab – Open Source Repository

Welcome to the Operating Systems Lab open-source repository!
This project contains clean, beginner-friendly C implementations of core OS concepts taught in university labs such as VTU, Anna University, and others.

✨ Made by students, for students. Learn by doing, and contribute as you grow.

📚 Contents

Category Folder Algorithms / Programs Included
CPU Scheduling scheduling/ FCFS, SJF, Round Robin, Priority
Memory Management memory_management/ First Fit, Best Fit, Worst Fit
Page Replacement page_replacement/ FIFO, LRU
Deadlock Avoidance deadlock/ Banker's Algorithm
Interprocess Comm. ipc/ Producer-Consumer, Reader-Writer

🛠️ How to Run

Each program is written in C and can be compiled using gcc:

gcc filename.c -o outputname
./outputname

Some programs use pthreads:

gcc thread_based_file.c -lpthread -o program

💻 Example Projects

  • ✅ scheduling/fcfs/fcfs.c: First Come First Serve CPU scheduling
  • ✅ ipc/producer_consumer.c: Synchronization using semaphores
  • ✅ deadlock/bankers_algorithm.c: Avoid deadlocks using Banker's safety algorithm
