***** 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. :)
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! :)
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
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 :)
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.
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.
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.
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.
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!
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.
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 :)
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.
On the slide at 8:31 you say that TCP is streaming orientated and as an example you give phone conversations. Wasn't UDP better for that? You want it real time and you don't want, if second 2 of the phone call get lost, it being mushed in between second 7 and 8.
+WolkieNL +Seb M After reading your comments, I see that the examples on the slide are a little confusing. I didn't mean to imply that e-mail protocols use UDP - this is not the case. I'm talking purely on a conceptual level: e-mails are separate chunks of communication (message-oriented) while a phone call is a continuous flow of communication (stream-oriented). I think it's best to put it another way: message-oriented is discrete, stream-oriented is continuous. Hopefully that makes more sense. Thanks for pointing this out!
I am one of the "mentally handicapped" that actually find the speed of the video optimal for me :) Please keep it up, most people on TH-cam talk way too fast
+Oliver Reipschläger I'm actually a Belgian man pretending to be a British person trying to fake an American accent. And you totally fell for it... MUAHAHA!
+PieterExplainsTech I had no idea you were from Belgium. I speak dutch as well, and my english accent is horrible so, good job on both your English and the Tutorial :D
+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.
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.
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 :/
Good video, but I got confused at the start from 0:40 when you mentioned "....wondered why it's possible that two applications can use the same internet connection at the same time..." does the two applications refer to as TCP and UDP?
I'd say that they do a similar job, but on different levels. There are, however, some subtleties that you shouldn't overlook. For example, the IP protocol doesn't provide any of the services that TCP provides to make transmissions more reliable, like acknowledgments or retransmissions. Then again, using TCP with a version of IP that also provides things like acknowledgments would duplicate functionality.
very nice video. i have a doubt: On whom it depends that which protocol will be used? i.e. if I want to stream a video from ESPN sports website or TH-cam, the video will be received by TCP/UDP will depend on ______? a. how video provider had programmed it b. how my application (chrome, internet explorer etc.) wants. c. dynamic, dependent on internet speed which option would be correct?
i'm not 100% sure about this, but I think an average video on youtube or ESPN will be transmitted via TCP, while a live streamed video will be streamed via UDP ( doesn't matter if a few frames get dropped ETC).
go ahead and adjust playback speed to 1.5...you're welcome
iii haave noo ideea whaat you are taaalking about
@@PieterExplainsTech 😂
@@PieterExplainsTech thats what heros do
@@PieterExplainsTechhahaha love the self awareness
nah 1.25 is better
I'd tell you a UDP joke but I'm affraid you won't get it.
That joke is great and don't let anyone tell you otherwise!
ywecur_ oh!!! packet dropd :P
better use tcp next time
ywecur_
I'd tell you a TCP joke but I'm afraid you won't get it in time.
ywecur_ **may or may not get it **
+ywecur_ I'd tell you an IP joke but I'm afraid you won't understand
Thanks so much, this was like 2 weeks worth of lectures in 11 mins! Well done!
lucky you
I found this after my computer network grades
This would make it much easier
More videos man! You are one of the few networking tutors I can actually understand lol.
Thank you! My lecturer was trying to explain this and had the entire room up in arms, decided to listen to this instead!
Great video but I suggest watching it at 1.5 speed.
Hahaha! genious!
***** Can you please provide some good resource links to back what you have mentioned?
***** Try 0.5 Oh my stomach XD

I think its great how he takes it slow. Guess it depends on preference.
Thank you! People like you, can actually explain what they are talking about, because they know what they are talking about.
are you still alive ?
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! :)
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.
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
before you, it was so complicated.
you made it very simple , that shows how well you understand this stuff.
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 :)
Very clear and precise. Good repetition of concepts when needed. Also a great line out of examples. Good job

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.

Love from Canada!
Best guide about protocols i've ever seen!
I like your brief and precise explanation. You made it clear and easy to understand.
Excellent refresher. Thanks for taking the time to make such quality, simple presentations..
Excellent video and explanation! @ 9:27 It's amusing how UDP still managed to send all the characters of each word in their correct order :-)
Fantastic video Pieter...much clearer than my lecturers! Keep up the great work

You make great videos sir. Simple, clear, direct, focussed - good job. Thanks for posting.
One of the best tutorial channel. Hope to see more from you. Thank you.
Congratulations! Excellent way of explaining things! It flows so naturally.
Very good one Pieter. Very helpful for people who are just stepping into networking.
30 mins before my test and I finally get it now, thanks!
Wow, very crystal clear, we need some videos like this more..
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 :)

Thanks for the video, you explain the best on entire TH-cam
You are really great at simplifying topics that others seem to bog down with to much tech language! Thanks so much
Top class explanation and presentation. Video editing and minimal layout was a cake.
Thank you!

PieterExplainsTech thanks the video was really helpful and you explained pretty well either way
WolkieNL he switched those parts by mistake. Because clearly, phone conversations is an example of UDP.
But in the case of UDP in phone conversations, it doesn't check the data and resend it if it is wrongly spelt.
Quickly understandable,very good explanation,keep it up sir we really want this kind
Great explanation. Very concise and simplistic for consumption.
I wasn't able to find a video on BGP, this is something I would love to get a clear explaination of!
I am one of the "mentally handicapped" that actually find the speed of the video optimal for me :) Please keep it up, most people on TH-cam talk way too fast
Really loved this video, was really insightful :) Your way of explaining things is also pretty solid!
Very lucid explanation of the concepts. Thank you.
Really nice :) Keep posting videos. Very interactive and easy to understand :)
Love your videos. Some of the most useful content I've found on TH-cam. Thanks
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.

he sounds like a babysitter talking to a toddler... which i dont have a problem with, as i am a total moron when it comes to this stuff xD
Top tip: Watch on 1.25x. Great content Pieter, keep making more!
Your videos are great. Please make more. Animations and explanations are perfect
It's just an awesome description you've given, keep going with good in-depth content.
cheers!
Hi from Brasil!!! Really good video, congrats man!
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.
This was a very buttery explanation , thank you so much and keep up the good work ..
Great explanation, keep going and posting videos on the greatly needed tech. stuff.
It very comprehensive and well explain the difference. Thank you for sharing
Speeding this video up by 1.25 makes your voice sound normal.
I just tried it
True! I should have done that before watching the whole video.
Nice trick!
Haha this was the first thing I thought when I clicked on the video... I had set it to 1.5.
thanks
5:40
Does it mean that UDP follows a packet switching and TCP a circuit switching style?
yes we can say that
no, it follows packet switching, it just contains metadata on how to arrange packets
This is crystal clear explanation for rookies. thanks.
Great job, great video. I watched it at 1.5 Speed, and it was PERFECT. Thank you!
fantastic video man! thanks for the thorough examples and well-presented info!
Amazing!
That is just amazing. Please continue making these videos
+PieterExplainsTech
For what kind of security reasons would some firefalls stop udp ? at 10:56
Thanks! Great explanation along with helpful visualisation through animated slides.
Just wanted to say thank you, I've been in IT for 25 years, I was learning about PCoIP and couldn't understand why they use UDP
Thanks for your illustrative instruction to TCP/IP.
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 :/
8:25 isnt that backwards?
thank you for this video. you are better then my teacher.
lol
I was searching for this info; you did a great and clear explanation^^ Thanks!
your videos crystal clear. please make a complete playlist for networking.
Good video, but I got confused at the start from 0:40 when you mentioned "....wondered why it's possible that two applications can use the same internet connection at the same time..." does the two applications refer to as TCP and UDP?
A wonderful Explanation, thank you so much Pieter.
u explained it much better than others
Sir, this video was extremely helpful! Thank you!
Cooooooool. Explained calmly. I like it.
Your videos are so helpful. Thanks so much.
Quickly understandable,very good explanation,keep it up sir we really want this kind
Great video but I suggest watching it at 1.5 speed.
I think u have interchanged the examples of tcp and udp ..And the rest of the video was really awesome
very nice vedio.i was preparing for TCP and found your video very helpful.keep the good work going.its really helping others.
Hey I need to study about the algorithms used in TCP and UDP. Do you know a place where can I get those.
The best comparison video, Thanks a lot
Thanks for the video, great explanation.. please keep them coming
Thank you, I've got a test and this was a perfect refresher. subbed for more!
Crystal clear. Thank you for sharing!
BEST VIDEO ON TCP/UDP
Nice presentation and informative every single word. Thank you
Hi pieter..........nice video , well explained in a simplified manner
best explanation of TCP vs UDP, thank you man!i needed this!
Thaannnkkkk youuu fooorrr theee videeoooo
Make more of these stuff!! U're awesome
These videos are great! Please make more. THE OSI model would be great!
You kept it very simple which I could understand. Thank you!!!

Then again, using TCP with a version of IP that also provides things like acknowledgments would duplicate functionality.
wow, your teaching was really interesting and i loved the explanation. Thankyou so much!
you have clear every thing so nicelly...thanks very much..
could you make videos explaining the layers of the network ?
It was very helpful and explanatory. Thanks a lot.
Great video. Can you do one video on what ICMP and how it is used? Thank you.
very nice video.
i have a doubt:
On whom it depends that which protocol will be used?
i.e. if I want to stream a video from ESPN sports website or TH-cam, the video will be received by TCP/UDP will depend on ______?
a. how video provider had programmed it
b. how my application (chrome, internet explorer etc.) wants.
c. dynamic, dependent on internet speed
which option would be correct?
i'm not 100% sure about this, but I think an average video on youtube or ESPN will be transmitted via TCP, while a live streamed video will be streamed via UDP ( doesn't matter if a few frames get dropped ETC).
nicely presented and explained.
looked up for my exam preparation and i'm happy.
Thanks
