TCP vs UDP - Explaining Facts and Debunking Myths

Explore the fundamental differences between TCP and UDP protocols in this comprehensive 20-minute video. Compare these Layer 4 protocols across four key dimensions: connection orientation, reliability, flow control, and overhead. Delve into common misconceptions, debunking myths about speed, security, reliability, and guaranteed delivery. Gain a clear understanding of TCP and UDP headers, their fields, and sizes. Learn how to interpret statements about protocol performance correctly and discover the nuances that make TCP and UDP essential for internet communication. Perfect for networking enthusiasts and professionals seeking to deepen their knowledge of these crucial protocols.

- Intro
- Pre-Requisites - OSI Model Layer 4
- Agenda for this video
- Connection Oriented vs Not Connection Oriented
- TCP is Reliable -- but what does that mean?
- Confirmation of Data Delivery
- Application is Aware of Errors
- Data Ordering and Sequence Numbers
- Notice I didn't say UDP is not reliable
- Flow Control & Bandwidth Utilization
- TCP has More Overhead, UDP has Less Overhead
- UDP Header, 4 fields, 8 bytes
- TCP Header, 11 fields, 20-60 bytes
- Dispelling Myths about TCP and UDP
- UDP is Faster ... Not Exactly -- Myth 1
- TCP is more Secure ... WRONG -- Myth 2
- UDP is Unreliable ... NOPE -- Myth 3
- TCP is Guaranteed Delivery ... Well, not really =/ -- Myth 4
- There is so much more to discuss with TCP
