Lec-22:Classical Problems of Synchronization–Bounded Buffer Problem | For GATE, NET,University Exams

Welcome to the Operating System Revision Series for GATE 2026! 🎯
In this lecture, we begin exploring the Classical Problems of Process Synchronization, focusing on the Bounded Buffer Problem (Producer-Consumer Problem) and its Semaphore-based Solution.

You’ll learn how producer and consumer processes interact while sharing a finite buffer and how improper synchronization can lead to deadlocks, data inconsistency, or race conditions. We use Semaphores with the wait() and signal() operations to ensure proper mutual exclusion and process coordination.

This lecture lays the foundation for understanding upcoming classical synchronization problems like Readers-Writers and Dining Philosophers — key topics for GATE CSE 2026, NET, and University OS exams.
