Operating Systems Course - Projects

Course Overview

This repository contains the project assignments for the Operating Systems course. The projects are designed to provide hands-on experience with essential OS concepts such as system calls, process management, inter-process communication (IPC), and synchronization. Projects 1 and 2 are implemented in C, while Project 3 is implemented in Java.

Projects

1. Ex1: System Calls, Basic I/O (C)

• Objective:
  • Learn to interact with the operating system using system calls with a focus on basic I/O operations.
• Description:
  • Implement a C program that reads from and writes to files using system calls (read, write, open, close, etc.).
  • Gain experience with file descriptors, non-blocking I/O, and error handling.
• Key Concepts:
  • System calls: read, write, open, close
  • File descriptors
  • Error handling and debugging

---

2. Ex2: Processes, Multiprocessing & IPC (C)

• Objective:
  • Learn about process creation, control, and inter-process communication (IPC).
• Description:
  • Write a program that uses fork() to create child processes and communicate between them using pipes or shared memory. Synchronize the processes and handle termination properly.
• Key Concepts:
  • Process creation (fork())
  • Process control (exec(), wait())
  • Inter-process communication (pipes, shared memory, or message queues)
  • Basic multiprocessing and synchronization

3. Ex3: Synchronization (Java)

• Objective:
  • Implement synchronization mechanisms to control access to shared resources in a multithreaded environment.
• Description:
  • Implement a solution to a classic synchronization problem (e.g., producer-consumer or readers-writers problem) using Java synchronization primitives such as synchronized, ReentrantLock, Semaphore, and Condition.
• Key Concepts:
  • synchronized keyword, ReentrantLock, Semaphore, Condition
  • Avoiding race conditions and deadlocks
