Operating Systems Lab Codes Repository

Welcome to our Operating Systems Lab Codes Repository! This collection has been meticulously compiled to serve as a practical resource for students, educators, and enthusiasts exploring the vast world of operating systems concepts. From process scheduling to memory management and synchronization, you'll find a variety of code examples to help illuminate complex OS theories with real-world applications.

What's Inside

This repository contains implementations of fundamental and advanced operating systems concepts, including but not limited to:

  • Process Scheduling Algorithms:
    • First-Come, First-Served (FCFS) (lab5fcfs.c)
    • Shortest Job First (SJF) (lab5sjf.c)
    • Round Robin (RR) (rr.c)
    • Priority Scheduling (priority.c)
    • Shortest Remaining Time First (SRTF) (srtf.c)
    • Multi-level Queue Scheduling (multi.c)
  • Memory Management:
    • First Fit, Best Fit, Worst Fit allocation strategies (first.c, best.c, worst.c)
  • Page Replacement Algorithms:
    • FIFO (FIFO.c)
    • Least Recently Used (LRU) (LRU.c)
    • Optimal Page Replacement (OPR.c)
  • Synchronization Problems:
    • Producer-Consumer (procon.c)
    • Dining Philosophers (dine.c)
  • Other Concepts:
    • Banker's Algorithm (bankers.c)
    • Peterson's Solution (pete.c)

... and many more examples covering various aspects of operating systems.

How to Use

Each file in this repository is a standalone C program demonstrating a specific concept or algorithm related to operating systems. You can compile each program with a C compiler like GCC. For example:

gcc -o fifo FIFO.c
./fifo

Replace FIFO.c with the filename of the code example you wish to compile and run.
