TCP vs UDP Explained | Top 5 Differences in Transport Layer | Computer Networks

It is the ultimate battle of the Transport Layer: Reliability vs. Speed! In this Computer Networks tutorial, we do a complete side-by-side comparison of TCP (Transmission Control Protocol) and UDP (User Datagram Protocol). Key Comparison Points Covered: Connection: Connection-Oriented (TCP) vs. Connectionless (UDP). Reliability: Guaranteed delivery & ACKs (TCP) vs. Best-Effort delivery (UDP). Speed & Overhead: Heavy 20-byte header (TCP) vs. Lightweight 8-byte header (UDP). Features: Flow control, Error control, and Congestion control differences. Use Cases: Web Browsing & Emails (TCP) vs. Live Streaming, DNS & Gaming (UDP).
