In this video, we dive deep into Data Link Layer protocols used for error control and reliable data transmission in computer networks. We’ll break down the three major Automatic Repeat reQuest (ARQ) protocols—Stop-and-Wait, Go-Back-N, and Selective Repeat—with real-world examples and animations to make learning easy and engaging!
🔹 What You’ll Learn:
✅ Stop-and-Wait Protocol – A simple but slow method where only one frame is sent at a time, waiting for an acknowledgment before proceeding. Learn its advantages and limitations.
✅ Go-Back-N Protocol – Uses a sliding window to send multiple frames before needing an acknowledgment, making transmission faster but requiring retransmission of all frames after an error.
✅ Selective Repeat Protocol – The most efficient method that only retransmits corrupted or lost frames, reducing redundancy and improving performance.
