Muzamil-663/OS-Kernel-Scheduler-Simulator

Operating System Kernel Simulator (C-Based)

Project Description

This project is a C-based Operating System Kernel Simulator that demonstrates core concepts of operating system design, including process management, CPU scheduling, and memory allocation. The simulator provides a menu-driven interface to create processes, manage their states, and analyze different scheduling algorithms in a controlled environment.

The project is designed for academic purposes to strengthen understanding of how an operating system kernel manages processes and system resources at a fundamental level.
