What is a Protocol? (Deepdive)

[@skwalex]

I've never seen anyone explain things as good as you do

[@satisfying.balls01]

because he really understands it xD

[@arkan7rb]

true

[@P.venkatamanikantaP.venkataman]

His headline is enough isn't it

[@viniciusleitepereira5571]

This Deepdive series is fire 🔥 Keep doing the good work, sir!

[@LazizbekYusupov92]

Man, he should go deeper and wider with a complete tutorial on Computer Networks academic level!

[@konradkos1981]

Would it be possible if you could describe Threads vs Processes and how Operating systems manage processes? It is one of the more difficult concepts and I think your talent in teaching would be of great use. Other videos confuse more than clarify because they all seem to contradict each other on minor details. You give a great explanation because you describe these concepts on a large scope and abstract away trivialities.

[@w花b]

Good idea

[@brucewayne2480]

Good idea, I'm genrally confused between the real thread (physical) and the virtual one , the meaning of thread in operating systems , When I create a thread in nodejs for example , does it mean that it will wait until a physical thread or virtual one runs it ? When I fork a process what happens in my cpu ?

[@Miles-co5xm]

@@brucewayne2480 just to make you more confuse, physical threads don't exist virtually, but virtual threads exists in physical when the realm changes from 3d to 2.5d, which makes os a software running on single thread and multiple virtual cores.

[@jothamprince8765]

Hi, I'm a second year computer science student and I cannot stress how much this video was helpful to me, it really came in a time when I was struggling to understand some advanced computer networks concepts, I was actually struggling to design a protocol when I didn't even know what It means, thanks a lot man, the explanation was very good, simple and precise, I really appreciate it

[@belalal1902]

Please make more (Deepdive) videos! They Are great and very informative

[@buckwheat2323]

I definitely like where these deep dives are headed. You have a wonderful way of boiling down complex subjects. My suggestions would be an exploration of SSL/TLS.

[@skeeberk.h.4396]

You're warming up to me, Finally Explaining stuff without a passive Condescending Tone , Amazingly Done 👍🏾

[@anthaguz]

This is possibly the best video about this topic I have ever seen, you are excellent at what you do! I appreciate the content and will keep visiting every time I can!

[@rajatchopra1411]

You made the server concept "click" for me. please continue this deepdive series as more topics need to be unraveled like this

[@nopsep3139]

I speak Spanish, and having subtitles helps a lot to be able to understand everything you're saying, because I know English, but at a medium level. Also the fact that you explain things so thoroughly, starting from the base, makes your content great, I will follow this channel forever and I will always recommend it, among the best alternatives.

[@madmushroom8639]

Great video! To even dive deeper: A very interesting part of TCP is also the Congestion Control to optimize bandwidth utilization. It is still a huge research field at e.g. Google and KIT...

[@MasterMathematicswithMatthias]

how could you explain things so clearly and speak so fluently.

[@ZeKof9300]

Man you make this so fun and easy to digest with the supportive visuals

[@black53342]

This series is proving to be the one is always wished for.

[@nieczerwony]

As computer/electronic engineer I was fed up with all this protocols/communications like this. UART, I2C, SPI, USB, ZigBee, BT or even CAN, but also many others. But with time I understood how much it helps when you go for higher level applications etc. GR8 lecture from yourself as usual.

[@apurbosarker112]

Your way of explaining things is the best I've ever seen.

[@vinaykumar-qe4zx]

This deepdive series is invaluable....please keep doing this

[@zaheer4511]

i think you're gonna finally taught me what networking is all about. I bet your 17 year old self is grateful to you!!!

[@lethalz4519]

Wow ! This is a great explantion and i like how you reference the RFC's . Great timing on this changed my whole paradigm on Protocols for life.

[@JordanPlayz158]

Anyone who goes through the time to read and implement those protocols (by reading the RFCs) are.... mad lads

[@mingxingchen3797]

Many people have understanding problem, so is this the video author. Protocol is just a way of communication between two parties. Very easy to understand. Just like two people meet one say "Hello", the other also say "Hello", one say "how are you doing today", the other say "Pretty good, how about you?"... Client and Server in communication have to follow certain protocol to communicate.

[@mukaddastaj5223]

I kid u not, i'm ready to confess my love for you! The way it made so much sense! I always wanted to study programming and software development but ended up majoring in networks & cybersecurity, which is kinda confusing for me😭 you gave me hope i can actually do this

[@anjuro]

Very informative video! If you end up making more I think going into how networks are structured might be an interesting topic (e.g. locally, when connecting to a website, in a lan configuration etc).

[@GeorgeValkov]

For network protocols, just grab Wireshark and see how they work. So far I implemented a UDP stack and a web server and it was easy. Also WebSocket. As a second step, reading the RFC helps a lot. Reverse engineering is a good way to start.

[@bendomino8476]

Oh man, I have no words but just an exciting feeling to finally understood or just at least get a glimpse of these fundamental knowledge and not just hacking stuff. Wherever you are, Thank you LiveOverflow.

[@OhMyJawsh]

Just an additional bit of information, whenever going into the TCP protocol. In the TCP 3-way handshake (SYN, SYN & ACK, SYN), all of those are controlled within the TCP header in a section called "control bits". There's a total of 6 control bits that you can choose from; URG (Urgent, used to indicate packet priority), ACK (Acknowledgement, used to acknowledge connection was successfully established), PSH (Push), RST (Reset the connection when a timeout or error occurs), SYN (Synchronization), and FIN (Used to terminate connection)

[@ananyamishra382]

please never stop making such videos

[@conando025]

A good topic for a standalone video would be what is a program and what happens when i execute it. Of course that's such a broad topic that no one video can do it justice but i feel like there is a big gap between the layman's understanding (an exe file that just does things when i click on it) to the understanding of the program being run with arguments and then getting loaded into memory and what do all play into this. I don't have to many concrete ideas but from what I can see in my fellow CS first year's is that this something they don't really have a grasp on and just take it a some magic

[@nikensss]

extremely unvaluable content. I would also been very grateful for having content like this available when I was in university. It also helps now to clarify ideas and better understand all these. Thank you very much!

[@jessechou9397]

Really, really great explanation. Loved the examples too - helped me finally understand HTTP requests. Keep it up :)

[@Radium_227]

I have been watching KZbin for a better part of my life and his video's 15 sec intro just made me subscribe love the honesty and motivation.

[@a11aaa11a]

This is useful even for seasoned web developers imo, at least it was for me personally. It's good to re-solidify fundamentals from time to time! I hadn't thought of e.g. the Twitter API as a protocol, but it's obvious in retrospect.

[@mrstark7491]

Great explanation!!! Please make more such videos on other networking basic concepts Cheers!

[@Makbetjuz]

Thanks for making this video. I hope that my comment from the last deepdive series video about what is a server partially helped you decide on this particular topic :)

[@PotatoGodzilla]

This is amazing as a web developer I'm very grateful for explaining it so well for me!

[@cloudjumper725]

Man. I'm not a natural in IT and it`s often hard to UNDERSTAND why things as they are. Unfortunately, a lot of teachers and professors just say "So, here is *some concept* works like this, used for this" and forget to explain why it does even exists. If there is a solution, there is problem it tries ti solve. Thanks for the explanation.

[@vietanhlehuu]

Amazing video, the way you explain things is the best. Please make more videos deepdive like this.

[@Code12x]

I didn't even watch it yet, but I would have LOVED to have had this video like 4 weeks ago when I started my research paper on Internet Protocols... anyways, can't wait to watch it!

[@aymane.superuser]

Thank youuuu, the best explanation ever. 16:15 takeaway.

[@nicof_2000]

Amazing video, I didn't really learn anything new, but your "style" of explaining things is really good.

[@FRSilent]

Charles Petzold's Code is a really great read imo that expands on this & goes over the historical context of shared communication protocols & their evolution. Worth a read! :D

[@VishalkrKamat]

Your video is so clear and detailed . loved it

[@a.for.arun_]

Thank you so much for this video. Much needed one for me. Please continue this deepdive as a series.

[@hakimmaher9467]

I really liked the video ! the word "Framework" is also a little bit confusing may mean some sort of "library" in programming language , may carry another meanings in the firmware and used in software design ..etc

[@denni_isl1894]

You are a gifted teacher. Period.

[@oufcoufc6700]

This video is really crazy, clearly explained everything with examples

[@YosiYosiro]

thank you, this is my favorite segment in this channel. Maybe next you can explain Service Bus, Message Broker, Serialization, Interface, and other jargon in IT that made people confuse. Thanks a lot for video.

[@esquilax5563]

Nice video! BTW, tip for at 2:00, "suite" is a loan word from French and is pronounced like "sweet"

[@danielh2833]

Love it! I'm hearing a Telematics lecture this semester and these Videos are a great addition to help my basic understanding of the subject. Thanks :)

[@arithmós_0x8]

I love this format! Awesome video dude 🤙

[@BarraIhsan]

I love the deepdive series so much! I never knew about protocol this far!

[@techfunwithaadil]

This is what i am searching for since 3 months thank you

[@waterflowzz]

Teachers in schools should be teaching the way you do, by logically explaining each step of the way but unfortunately the main method of teaching in schools is by memorization. Much of that is do to the fact most people don’t know how to break down the thoughts to the “smallest atom”. Awesome explanation. You should be a university professor.

[@shubham_srt]

a video that i wish existed back when I was learning protocols, great job !!

[@Agnubis]

Great video as always. I've often found the concept of protocols a bit enigmatic but this was really helpful!

[@satyaranjansahu336]

Another great explanation!. Kindly make a deep-dive video on OSI Model.

[@jingkangloh7710]

This video is the answer to my search for the question for so long!

[@type3gaming851]

This is the best explanation I've seen about this topic! Good stuff man

[@princemehra12]

I love how you have explained the Protocols

[@amirlatifim]

Bravo! Simple and at the same time magical!

[@foor]

This was a very good video explaining protocols in the finest details! I would definitely show this to a friend if they asked me about a this.

[@gellyicev2]

Bro I just got into cyber security and I was confused about protocols. This video helped me a lot 🙏🙏

[@HenryLoenwind]

UDP is like sending postcards. You cut whatever you want to send into small pieces, write it onto the back of a postcard and send it. The receiver then has to sort through a whole stack of postcards and puzzle out the order and if some are missing or not. TCP is like making a phone call. You call someone and get 2 continuous channels where not only every word you say is delivered in the exact same order to the recipient, but you also know if the call is established or ended. IP is like UDP, but the postcards only have street and city but not apartment number or recipient name. The postal service doesn't care about those, they only are needed after the postcard has reached the destination address. That's why IP is used as a layer under both UDP and TCP.

[@arunprashanna7494]

Thanks for the good video. It cleared many of my doubts.

[@devchannel5232]

I struggle a lot with understanding hardware documentations for microcontrollers. I don't know where to begin, because everythings just seems to be cryptic or only for extremely clever people xD. Maybe u can make a video, how and where to start with hardware programming/microcontrollers, hardware hacking etc. This would be extremely helpful^^. Great video!

[@Zakurbeltza]

Very nice explanation, helpful to capture get a grasp on a big picture about protocols. I am now learning about the in HTB academy and I've found it very insightful. Thanks!

[@dharma01v]

Excellent explanation - clear and concise!

[@Ogyfxsfbki643]

This kind of videos are very very cool 👌 I love it 💚

[@kim92se64]

Yep, That's what I was looking for !!! Awesome work

[@zFake]

This is such a great video. It helped me a lot to consolidate my knowledge and to see learning from a new perspective. Thank you.

[@coolcha]

You are such a good teacher. Thank you for your videos.

[@TheCameltotem]

Love this series. More of anything please!

[@benfrese3573]

More Deepdive please. Amazing content!

[@GreenClover0]

Very good video. I actually have a short oral exam in two days of how UDP, TCP and some others exactly work and this video was very helpfull :^)

[@Bananabeacon]

Thanks! I love figuring out exactly how things work and this really helped me with that!

[@whtiequillBj]

it would be interesting to hear your thoughts on the QUIC protocol. As well as if you think it could superceed TCP in time. Also a video on QUIC (RFC 9312) seems like a nice progression from a video on TCP

[@AshtonSnapp]

Just went and looked QUIC up - seems interesting!

[@dannihijacked2508]

I agree

[@igreeuropa]

Thank you im in the industry and this is refreshing.

[@金志坚-d9w]

Thank u for the informative video! It really helps me to understand what is protocol.

[@Snoopydogsz]

You have the best explanation skills! Thank you for this!! :)

[@HarshJhaver]

Great video,love it . Would love to see a video about certificates and their working

[@gustadev276]

"Protocols are important to computers like language are important to humans." - what a beautiful message lol, this almost makes me cry 😁

[@_TravelWithLove]

Vielen lieben Dank für deine inhaltsreichen und intelligenten Videos !! Educational und wisdoms filled !! Awesome stuff !! Greetings from California … Ich wünsche dir euch gute Gesundheit, Erfolg und Freude !! Much Love ✌️😎💕
