CSL204 Operating Systems Lab programs

Welcome to the CSL204 Operating Systems Lab Codes repository! This repository contains various Operating Systems lab programs implemented in C.

📝 Preamble

The course aims to offer students a hands-on experience on Operating System concepts using a constructivist approach and problem-oriented learning. Operating systems are the fundamental part of every computing device to run any type of software.
