🧠 Operating Systems Lab in C (OSL-C)

Welcome to the Operating Systems Lab repository! 🖥️
This repository includes various OS-based programs implemented in C, covering core concepts such as process scheduling, memory management, synchronization, and system calls.

---

📘 About

This repository serves as a hands-on resource for understanding key Operating System principles through practical C programs. Ideal for students, developers, and anyone interested in systems programming.

🔍 Key Topics Covered

🧾 Process Management

• FCFS_10.c: First Come First Serve scheduling
• FIFO.c: Page replacement using FIFO algorithm
• FSFC.c: File system with First Fit allocation
• First_Fit.c: Memory allocation using First Fit
• Bankers_Algorithm.c: Deadlock avoidance using Banker’s algorithm

🔁 Process Creation & Termination

• Exp-04(Fork).c: Demonstration of fork() system call
• Exp-04(Wait).c: Use of wait() and exit() for child-parent synchronization

🔄 Synchronization

• Producers_Consumers.c: Producer-Consumer problem using semaphores

🖥️ Shell Scripting

• EXP_02.sh: Shell script demonstrating basic Linux commands
• Basic_Terminal_Commands/: Collection of commonly used Linux terminal commands

📊 Experiments

• Experiment-03.c: Custom logic (based on course experiments)

---

🛠️ Requirements

• GCC Compiler (e.g., sudo apt install build-essential)
• Linux OS (recommended)
• Basic understanding of C and system calls

---

🚀 Getting Started

🔧 Compilation & Execution
