***** Try 0.5 Oh my stomach XD

[@Mukeshsharma-pl5wg]

***** Bro in my book Computer Network by Andrew S. Tanenbaum UDP have 8 bytes header and TCP have 20 bytes header which is correct as we are comparing both the protocols. yeah IP header is 20 bytes for both because It has to be same you are comparing the message that have been delivered and he is talking about the packet header of these two protocols only without including IP header so he is also right. correct me I am wrong. :)

[@LosEagle]

I think its great how he takes it slow. Guess it depends on preference.

[@LosEagle]

More videos man! You are one of the few networking tutors I can actually understand lol.

[@AndyBlair]

Thanks so much, this was like 2 weeks worth of lectures in 11 mins! Well done!

[@ruialves92]

lucky you I found this after my computer network grades This would make it much easier

[@scottalexanderwong]

Thank you so much for making these videos. Incredibly helpful. I bet there is a sizable boost in general productivity from exceedingly informitive videos like this

[@coolstorybro6154]

Very clear and precise. Good repetition of concepts when needed. Also a great line out of examples. Good job

[@amx2311]

Watching this at work with sound down. I don't know how you sound, but subtitles pick up what you say very well, so thanks for speaking so clearly.

[@garyknowles5705]

You make great videos sir. Simple, clear, direct, focussed - good job. Thanks for posting.

[@haleycooHal]

Thank you! been working on trying to understand ports and protocols for a couple days now, just wasn't quite grasping the concept but you cleared it right up for me! Seems like such an easy to understand concept now

[@matondocska]

Great work! Thank you very much. I was told about this topic for hours and hours at school, did not get it. Here you come and in 11 minutes I DO understand. Hats off, and keep the vids coming :)

[@nick56538]

Thank you! My lecturer was trying to explain this and had the entire room up in arms, decided to listen to this instead!

[@NetworkAdvisor]

Excellent refresher. Thanks for taking the time to make such quality, simple presentations..

[@ryanlovewow]

Your videos are great! And incredibly informative! I appreciate the effort put into making the videos. You are VERY easy to understand too! Good job, hope to see more videos soon :)

[@tgardner5968]

You are really great at simplifying topics that others seem to bog down with to much tech language! Thanks so much

[@Oxserz]

Thank you very much for the video man! I realize the audio was slow but it gave me time to process and understand the details! You do a great job at explanations with audio and the video components! Its amazin eh! Cheers! Love from Canada!

[@UltimateBass2]

thank you for explaining it so clearly! my lecturers could never get this through to me!

[@cajogos]

Really loved this video, was really insightful :) Your way of explaining things is also pretty solid!

[@rayselM]

This is an amazing video. Very easy for a super novice like me to understand. I like the slow pace. It allows me to fully absorb the content.

[@DanielHawkKennedy]

Very good video, formal, animated, good sound, high quality, finally a respectable video, thank you so much, this is a good start to further investigation about, for example what contain the headers of segments, how TCP corrects the lost of packages...etc. It could be nice to see this explanation in this kind of videos.

[@loopuleasa]

Top class explanation and presentation. Video editing and minimal layout was a cake. Thank you!

[@OroianRares]

Congratulations! Excellent way of explaining things! It flows so naturally.

[@kennethhowell5291]

Thank you! People like you, can actually explain what they are talking about, because they know what they are talking about.

Fantastic video Pieter...much clearer than my lecturers! Keep up the great work

[@safweneful]

before you, it was so complicated. you made it very simple , that shows how well you understand this stuff.

[@rinaldogarcia5223]

Dear Pieter, I did a test to work in the public sector and one of the questions was to describe how TCP / IP works, and certainly this video help me a lot with this question. Thank U.

[@MicheleTurchiarelli]

Best guide about protocols i've ever seen!

[@Xennon1117]

I like your brief and precise explanation. You made it clear and easy to understand.

[@hmxmghl]

One of the best tutorial channel. Hope to see more from you. Thank you.

[@user-je1if9sp4i]

Very lucid explanation of the concepts. Thank you.

[@JoshuaRaichur]

Thanks! Great explanation along with helpful visualisation through animated slides.

[@chrissylarson6232]

I wasn't able to find a video on BGP, this is something I would love to get a clear explaination of!

[@RedLoopster]

As everyone's saying, great video! Have an exam tomorrow, saved a lot of time by watching this, couldn't really understand it from only texts. So THANKS! :)

[@sampathkangankar]

Wow, very crystal clear, we need some videos like this more..

[@anandvats9508]

Very good one Pieter. Very helpful for people who are just stepping into networking.

[@MrSid20000]

Thanks for your illustrative instruction to TCP/IP.

[@poojajaldu2929]

Quickly understandable,very good explanation,keep it up sir we really want this kind

[@namle-br8ju]

It very comprehensive and well explain the difference. Thank you for sharing

[@PieterExplainsTech]

Great question. Originally BitTorrent only ran over TCP. In 2008, the µTorrent team developed µTP, a UDP-based protocol for BitTorrent. Since UDP doesn't offer in-order delivery (among other things), µTP implements this functionality in its application layer. If you want to read more about how and why BitTorrent runs over UDP, you can find some relevant links in the video description.

[@ErKenneth]

Great explanation. Very concise and simplistic for consumption.

[@blindlygoing]

Love your videos. Some of the most useful content I've found on KZbin. Thanks

Almost all the comments here tell the same thing, Its an amazing video. I do want to point out the example that you mentioned for TCP and UDP, it just cleared the concept for me. Thanks.

This is one great video, few years Ago while first to Haiwei vision in 2012( manufacturer of video encoder), I was always asking why TCP and UDP

[@satyamurthygunturu403]

your videos crystal clear. please make a complete playlist for networking.

[@PieterExplainsTech]

Thank you! Some services like DNS can run over UDP as well as TCP, but I can't come up with an example of one transport protocol being wrapped in the other. What do you think the benefits would be of wrapping TCP traffic in UDP packets or vice versa? I can't think of any right now. I only see more communication overhead.

[@elegantuser1090]

Nice presentation and informative every single word. Thank you

[@0anant0]

Really appreciated Thank you. Explained well and smooth

[@riankrishandi]

Crystal clear. Thank you for sharing!

[@chrisvsworld]

These videos are great! Please make more. THE OSI model would be great!

[@PieterExplainsTech]

UDP and IP have different tasks and are often used together. IP helps deliver packets to the right computer. Transport protocols like UDP help deliver packets to the right application on that computer. If we didn't have transport protocols, you wouldn't be able to use Chrome and Dropbox at the same time.

[@xingjianwang1894]

This is crystal clear explanation for rookies. thanks.

Thanks bro, I'm brazilian and I need learn this informations, I don't understand English very well, but, thank you I'm learning more that my brazilian teacher and look he speak in Portuguese, so thanks man!!! You're awesome.

[@conc3pt3]

Thank you so much! This helped a lot in my term paper.

best explanation of TCP vs UDP, thank you man!i needed this!

[@waxvapour]

nicely done ..,.. thank you sir ..u just simplified the heck out of it..,

[@BradenJohnYoung]

This really cleared up a lot for me. Thank you

[@dncam]

I just had a test on this stuff! Used your videos to help me study. Thank you!!!!

[@karleisheim8043]

This and your other videos are gorgeous! Can you pls make others where you explain the complete 5 layers of the "internet connection"? It would be really nice because when I look in the internet, everybody explains it different that it's really hard to understand :/

thank you for this video. you are better then my teacher.

[@ephraimnjoku4431]

lol

[@ankitprajapati3768]

Cooooooool. Explained calmly. I like it.

Thanks for the video! But the voice sounded a little creepy at the start until I got used to it XD

+黒い星 It sounds like a British person trying to fake an American accent, to me.

+PieterExplainsTech I could hear a bit of the accent coming out, but that is the best American I have heard so far coming from a non-English speaking person.
