TCP vs UDP - Explaining Facts and Debunking Myths - TCP Masterclass

TCP and UDP are the predominate Layer 4 protocols that have been used since the dawn of the Internet. In this video, we discuss TCP and UDP without getting bogged down with jargon or incomplete definitions.
We compare TCP and UDP across 4 dimensions:
- Connection Oriented vs Not Connection Oriented
- Reliable vs Unreliable (although, I don't like the term "unreliable" here)
- Flow Control vs No Flow Control
- More Overhead vs Less Overhead
Then we discuss and dispel four Myths about TCP and UDP:
- UDP is Faster
- TCP is More Secure
- UDP is Unreliable
- TCP is Guaranteed Delivery
A note about the myths:
As I mention in the video, a lot of what makes these "myths" is how you interpret the words -- in the end, it could all come down to syntax. This video is a teaching tool, I mean to teach you (the viewer) about TCP and UDP, and if this video can lead you to understand how some interpretations of "UDP is Faster" is correct, and some interpretations of "UDP is Faster" is incorrect, then I will consider my goal a success.
Correct Interpretations of "UDP is Faster": UDP has a higher maximum potential bandwidth, UDP has less overhead, UDP has less serialization delay, UDP has less inspection delay
Incorrect Interpretations of "UDP is Faster": UDP packets move faster than TCP packets, UDP always has faster throughput, UDP has no latency

01:15 - Agenda for this video
01:33 - Connection Oriented vs Not Connection Oriented
03:52 - TCP is Reliable -- but what does that mean?
04:07 - Confirmation of Data Delivery
04:45 - Application is Aware of Errors
05:41 - Data Ordering and Sequence Numbers
07:55 - Notice I didn't say UDP is not reliable
08:08 - Flow Control & Bandwidth Utilization
10:30 - TCP has More Overhead, UDP has Less Overhead
11:56 - UDP Header, 4 fields, 8 bytes
12:21 - TCP Header, 11 fields, 20-60 bytes
13:27 - Dispelling Myths about TCP and UDP
13:53 - UDP is Faster ... Not Exactly -- Myth 1
14:47 - TCP is more Secure ... WRONG -- Myth 2
15:48 - UDP is Unreliable ... NOPE -- Myth 3
16:52 - TCP is Guaranteed Delivery ... Well, not really =/ -- Myth 4
17:55 - There is so much more to discuss with TCP

📺🧩 TCP Masterclass: ru-vid.com/group/PLIFyRwBY_4bS-PQZoF0UySdG0sH9VA0bn 🚨📢 Announcement: *I'm creating a full Networking course!* Details --> pracnet.net/networking 👉👉 Enroll now for *discounted early access* to the course and a chance to help shape its content. 📺🕸 Module 1 of the course is *free* : ru-vid.com/group/PLIFyRwBY_4bRLmKfP1KnZA6rZbRHtxmXi But what about the TCP Masterclass? I have about 10-12 lessons scoped out for a comprehensive TCP Masterclass, and I'd love to create it at some point. When I released the first three lessons, I offered a challenge: If any one video garnered 100k views in the first 6 months, I would create the full TCP Masterclass. Unfortunately, we didn't meet that goal, so I had to prioritize other projects. But I haven't given up hope! *If you are interested in seeing the full TCP Masterclass developed, then the best way to bring that to fruition is to spread the word about this content*. Doing so will help others fully understand TCP and UDP and bring me closer to committing to creating the full series... Plus, think of all the Internet Points you can get for sharing this series (likes, karma, follows, etc) 😉 If you share this series, please use this link: ru-vid.com/group/PLIFyRwBY_4bS-PQZoF0UySdG0sH9VA0bn Otherwise, I genuinely hope you got a lot out of the first three lessons. Thank you for all the encouraging words in the comments. =)

Congratulations! I am from a Non-IT background and trying to enter the IT industry (Cyber Security - SOC Analyst).. Is it possible if you can share a couple of question you were asked in your interview.. Would be of great help. I gave a mock interview and could answer only 40% of the questions asked as per the feedback and major questions were from Networking basics...Thank you.

Bruh I just happened upon this channel and I've liked and subscribed but I HAVE to also comment. That was one of the most incredibly clear, informative and concise explanations I've ever heard for a more complex (at least in my mind) IT topic, let alone for something in Networking. I feel like I just learned not just listened to but actually learned about 3 hours of material in 20 minutes haha. Thank you for this!

@cslb38 Год назад

Great to see you back Ed, and we are certainly hoping this series gets traction. You've helped my study so much with your content, like the mastery subnetting, etc. I know personally I will be doing my part to get the word out. Thank you much for your efforts bro!
