An Operating System (OS) Lab provides hands-on practical experience in understanding core OS principles, hardware resource allocation, and kernel mechanics. Students use Unix/Linux environments to simulate and implement critical system functionalities.

Core Areas of Study

Process Management & Scheduling: Writing programs in C to implement CPU scheduling algorithms (e.g., FCFS, SJF, Round Robin) and managing processes using system calls like fork(), exec(), and wait().

Inter-Process Communication (IPC): Exploring data sharing between concurrent processes via pipes, message queues, and shared memory.

Deadlock Management: Simulating deadlock prevention and avoidance techniques, such as Banker’s Algorithm.

Memory & Storage: Implementing virtual memory replacement algorithms (e.g., FIFO, LRU) and disk scheduling (e.g., SCAN, C-SCAN).

File Systems & Shell Scripting: Using Linux CLI for automation, directory navigation, and file security management
