IPC Models and Race Conditions
Learn message passing vs shared memory and why uncontrolled sharing creates race conditions.
Inter-process Communication and Deadlock
Understand safe cooperation among processes using synchronization primitives and deadlock handling.
Learning objectives
- - Explain race condition and critical section
- - Use semaphores for synchronization
- - Apply classic IPC patterns
- - Analyze deadlock and Banker's algorithm
Topics in this chapter
20 min
Critical Section Solutions (Busy Waiting and Beyond)
Compare lock variable, strict alternation, TSL/XCHG, Dekker, and Peterson approaches.
Semaphores and Producer-Consumer
Use wait/signal operations to avoid race conditions and coordinate bounded buffers.
Readers-Writers, Dining Philosophers, Monitors, Pipes
Connect classic synchronization problems to practical communication mechanisms.
Deadlock, Prevention, Detection, and Banker's Algorithm
Master deadlock conditions and strategy families, then apply safe-state reasoning.
