In this video, we explain the Critical Section Problem in Operating Systems — one of the most important concepts in process synchronization.

🔹 What is a Critical Section?

Code segment where processes access shared resources.

Why uncontrolled access causes race conditions.

🔹 The Critical Section Problem

The challenge of ensuring only one process is in its critical section at a time.

🔹 Requirements of a Solution

Mutual Exclusion – Only one process in CS at a time.

Progress – No unnecessary blocking; fair choice of process.

Bounded Waiting – No process waits forever.

🔹 Solutions Overview

Software algorithms (Peterson’s, Dekker’s, Bakery).

Hardware support (Test-and-Set).

OS synchronization tools (Semaphores, Mutex, Monitors).

This tutorial is perfect for students preparing for Operating Systems exams, interviews, or anyone learning concurrency control.
