An interactive, educational web application that visualizes core Operating System concepts including CPU scheduling, memory management, and file system operations.

A C++ based, in-memory virtual file system simulating unix-like file operations for learning and research.

In this project, you will learn the basics of threading a process. You will see how to create threads and you will discover mutexes

My solutions for the book Operating System Concepts by A. Silberschatz

QBox is a secure file-sharing service. It is a customized version of the popularly available VSFTPD server.

Practice implementations of Operating System concepts – processes, threads, scheduling, synchronization, memory management – with Java.

Hospital ER Scheduling Simulation - Python + Flask + Web Dashboard. Models OS concepts: priority/FCFS/Round-Robin scheduling, multithreading, mutex synchronization, IPC pipes, aging (starvation prevention), memory pool management, and real-time SSE-driven visualization

In this project, you will be developing a program to check the file system consistency. The program, called as fcheck, reads a file system image and checks its consistency. When the image is not consistent, fcheck should output appropriate error message.

A C implementation of the Banker's Algorithm — an OS resource-allocation and deadlock-avoidance algorithm that computes allocation/max/need/available matrices.

Interactive web-based operating-system simulator: CPU scheduling (7 algorithms), virtual-memory paging (per-process page tables, 4 replacement algorithms, page faults) and blocking I/O on one logical clock. Pure-Python core, thin FastAPI layer, no-build HTML/CSS/JS UI with live Gantt, memory map and metrics.

Python simulation of lottery-based CPU scheduling, where separate processes hold tickets and the scheduler determines execution order through random ticket selection

UNIX-like virtual file system in C++ — inodes, file descriptor tables, system calls, permissions, and reference counting implemented from scratch.

This repository contains comprehensive resources for the Operating Systems course taught at FAST NUCES Karachi, typically offered in the 4th semester of the BSCS program.
