Computer Networking (Deepdive)

[@J0R1AN]

Less related to networking, but another video idea in this style might be explaining the difference between Encoding, Encryption, Hashing etc. Those terms get misused a lot and are really useful to understand

[@NoxiousPluK]

Just like authentication and authorization

Taking a minute to appreciate the video production quality with all that animations and actions in tile bars, OG work

[@lilyydotdev]

Can't wait for you to explain routing! This video was great :)

[@NoblePineapples]

Been watching your content for a couple years now and I am absolutely floored with the change in quality and presentation you've made over time. I am excited to see what you create in the future. I have been a big fan of your Minecraft stuff, it used to be a big part of my life way back in the alpha days when a friend and I used to run a server. Edit: The advertisement at the end was awesome!

[@rasmusmose8059]

Always great to watch your videos!

[@gradientO]

Absolutely loving these Deepdive series

[@malingatembo8850]

Layer 6 never looked this good! Amazing presentation!

[@mu11668B]

Ngl even the ads on your channel are one of the best I've ever seen! Great work!

[@1newcyber]

I love the way you have just explained things in details, as an ethical hacker/Pentester I love the small details which don't seems to matter but they matter a lot.👍👏👏

[@0xbro]

Damn! The "LiveOverfont" ad is cool AF and the font itself fit perfeclty! Each new video is more and more enjoyable to watch, keep it up!

[@MTG-BuenosAires]

this was one of the best explanaition of how the TCP/IP protocol works. Thanks for it

[@MuhammadZairZERO]

this is what i have been missing in my learning journy. Thank you liveOverflow. And please , never quite making these videos. This is what i need.

[@hunterdapenguin]

you are making me starting thinking i know everything about computers obviously I don't but dumbed down explanations like this makes it so everything just makes since and helps me understand better with what I don't know thanks for making these videos man : )

[@lightingman117]

I don't understand why all the other video's I watched on this topic didn't just say go read RFC 791, RFC 9293, & RFC 9112 and now you know how things work. Thanks for finally clearing up how things actually work!

[@AbuIshaq1441]

one of the best expalanation ive ever seen about ISO/OSI Modell

[@himashhimash6017]

One of the best-ever explanations for layers ....

[@vidalion]

I was just assigned uni coursework on this very topic, video timing couldn't be more perfect. Happy New Year!

[@glq-xz9de]

i have some basic concept about 4-layer of computer network. but this video still impress me alot ! what a wondeful discovery of journey in computer network ! really high quality video !

[@universal4334]

Wah! Appreciate your effort. It's been years that i was thinking how tcp talking to tcp possible. You cleared out that abstraction.

[@mikeyjohnson5888]

I have the model down through rote memorization but I must say your explanations make it far more intuitive.

[@shin-jo2801]

you explained this sooooo good. makes me understand more about what my uni prof was trying to explain for the past month or so in just 13 minutes

[@claasdeboer1843]

The layer explanation using little humans that all have their own task gave "Sendung mit der Maus" Vibes and i love it!

[@swetanksoni3521]

best simplified video ever on Computer Networking... I hope you will continue to add more content on "General Security Education".. i will definitely share this over my network. Amazing Work!!!!

[@soyitiel]

Ironically, I think this video spoke to me. You've convinced me: it's OK not to know everything that's going on under the hood

[@flyviawall4053]

I always have an analogy in my head: a person sitting in a room without window, only communicate with the rest of world through a small hole. you can only send/receive go chess one by one. Then, how to solve problems like: information integrity, addressing, multiplexing etc? that’s the OSI model. In my opinion this analogy is quite accurate for electronics communication, meaning almost all these devices using wire and electrical signal to talk(Ethernet, TTL, SATA etc.) face to same problem/concept(or wireless connection mostly abstract a wire).

[@feelsunbreeze]

Such a beautiful explanation!

[@Shuvooa]

Your videos I always look up to. Please make series on Networking. We are badly in need of it.

[@losocio1000]

You explained this way better than my uni prof. Thanks!

[@amarboparai4159]

Best explanation about computer networking on KZbin.

[@Emilybiubiu]

This is the greatest video for explaining networking.

[@gustavosimoes9755]

I just start watching this video and I already gave a like for 2 reasons. First and more important it is a LIveOverflow video, so it is guarantee that it would be a super hight content quality Senconde and funniest, the work this guy did to record himself being a computer and send and receiving message hahahahaah

[@ThePowerRanger]

Loved the ad. Border Gateway Protocol(BGP) would be a nice topic.

[@yousifradhi2940]

"You can accept blackboxes, but never be satisfied with blackbox" I liked this point of view

[@Shhluger]

It clicks only when I watch your videos! Thanks for sharing your understanding of this world!

[@SwordQuake2]

Awww, I really hoped you'd explain OSI layers 5, 6, and 7. I never understood why they need to be separate.

[@benfrese3573]

I agree, a deeper dive into the other layers would be much appreciated.

[@dusdee3315]

Layers 5-7 I could understand why they were initially separated, because there used to be separate protocols for session management (5) and data transformation (6). I don't think the ordering of the upper 3 layers is as important anymore because now many things are just HTTP REST API's of some sort. Sessions are often managed by the application themselves by using Cookies, bearer tokens (JWT) or some other stateful/stateless implementation. And while TLS is regarded as a Layer 6 protocol, doing things like JSON, XML, YAML transformation can apply here too. I think the utility of being able to cram anything into a TCP connection on top of HTTP being a simple request/response model helped it gain popularity and with respect to an HTTP stack, separating "Application" into 3 layers is not very useful as it shouldn't concern Network Engineers who should be focused on layers 1-4. Just the same as how developers shouldn't be worried about bits-on-the-wire and how switches/routers work.

[@KRIGBERT]

I find that I'm best at teaching the things I've struggled with myself -- apparently this isn't just true for me. Great video :)

[@nickravesh]

Good work, it was helpful and easy to understand. I also loved the small animations you created. for the suggestion I would say SSL and different kinds of it are confusing for me, I think it's worth a video. Thanks!

[@MasonSchmidgall]

I can see why you did it, but even implying for simplicity that switches look at IP addresses is definitely going to make any network admin cringe. However, the main point of the video is that most hackers don't need to know how their packets are transmitted and just need to know general information about how the protocol works. Since accepting abstraction as a hacker (most the time) appears to be the main thesis of this video, this video works. Networking can be a very dry topic. Networking 1 was the only class I've ever taken where the professor had to give us a 5 minute break in the middle so we didn't fall asleep. And that was only the first 3 of ~16 total credit hours worth of classes I needed on networking for my undergrad. So tl;dr: This video is for hackers who don't know anything about networking. It is a deep dive, but networking is so deep a subject that this barely scratches the surface.

[@J0R1AN]

The LiveOverfont looks really good!

[@gmeister3022]

Love the Deepdive series. Please, keep it up.

[@_CryptoCat]

Awesome as always! Very entertaining advert as well 😅

[@rebontadeb]

[@shriyanshgupta9951]

Thank you LiveOwerflow , I was looking for this exact video , I was not able to understand it before but not its all clear !! Thanks a lot !! I hope you will keep this good work up !! 👏👏👏👏👏👏

[@Code12x]

Your explanations are some of the best out there! I'm looking forward very much for the tunneling video, I already know it'll be awesome! Also, ever since I got Liveoverfont, I've been programming 10x more efficient!

[@FalcoGer]

it sometimes is interesting to see the protocol in order to break it. It isn't always the application layer with the exploit, the protocol itself can also be vulnerable, such as sending strange URLs and URIs to a webserver attacking the http layer implementation, or SYN flooding or SYN port scanning attacking the TCP layer directly without any application ever knowing about that it's happening because a full connection is never made.

[@supernovaw39]

This is amazing! You're doing a good job at explaining it and making it seem not complex like it does at first.

[@libyanpro9621]

You make every thing easy to learn , Thank you for that i hope you never stop , i realy enjoy

[@benfrese3573]

Very good video again. This is top-tier educational content and I can't wait for the next one. Your mum must be proud!

[@Nanagos]

That ad at the end is hilarious, I like it 😅

[@naruto5437]

this is amazing ...thanks for putting hardwork and making this great content free

[@calmocean3200]

[@LeBogo]

This is the perfect video for learning for my networking exam. Thanks! :D

[@homere3931]

Again an awesome video! You really have a talent to explain things, thank you so much for this. Since you asked for a topic suggestion, I always struggle with certificates 🤷‍♂

[@pauleth]

you have brought yourself to the next level

[@anamoly01]

Great video sir 👏👏 the hackers touch is super. please pick “sys calls” as topic for next as it is confusing to know how sys calls interacts with application in various operating systems. i vaguely know there is a lot of common things

[@jacolansac]

Dude. Your explanations are fantastic. Congrats and thanks.

[@CosmodiumCS]

love the advert at the end ha! great video as always :D

[@shell102]

loved the font ad at the end !

[@urrahman196]

Great video. Please make such kind of easy understanding video more on networking & (ssh, socket etc) stuffs

[@choisecurity]

What a great content. Really wish I had these type of resources back in school. I had to buy a notebook and draw all of these concepts with my shitty drawing skills to make my brain understand the concepts. Textbooks and professor presentations are nice, but these visual representations are great. Really helps students to understand abstract concepts with real world graphics.

[@rizkynathamael5333]

I like liveoverflow because this make me easy to understand

[@marianonicolini8119]

This series are insane, thank you so much

[@kennedyIAM]

Very well explained especially on ports

[@blackswan2881]

Thanks for making these videos. it really helped me to understand the concepts

[@Jorfy]

Bro i hope he makes like really indef videos about some of this stuff its all so intresting and he makes it so anyone can understand it

[@TheGrimravager]

Reading the title got me so hyped. I've been wanting to learn more about networking for a while now and have so far struggled to find comprehensive resources that connect well for me. (No pun intended). I've yet to watch the video, but I've already got this feeling it'll be the thing Ive been looking for. Thanks LiveOverflow, please keep making awesome content

[@lonnybulldozer8426]

I recommend the textbook, Computer Networking: A Top Down Approach. This is the resource you've been looking for.

[@TheGrimravager]

@@lonnybulldozer8426 Thanks, I'll check it out!

[@Ogyfxsfbki643]

That's what I'm looking for... Simple , visual , close of my mind , not dive into technical So cool 🆒😎

[@scope_sweeper]

This is so much better than what my networking teacher told me

[@cyrustakem7993]

damn, that end ad was super cool

[@kipchickensout]

War schon verwirrt dass da deepdive stand und es war nur ein kurzes video :D sehr oberflächlich joa aber gutes video

[@einsjannis]

The liveoverfont ad is genius haha

[@ndm13]

The thing that made networking click for me more than anything else was looking at full software implementations like overlay and alternate networks. Coming from Java, the I2P source code went a long way. It might be nice to cover it from this perspective, as it not only recreates the different layers but also actively addresses some common problems as security issues.

[@yerramreddyvamsidharreddy5882]

I just commented that I want a video on osi model for your video on http protocol. well my wish was granted 😂😊

[@AshtonSnapp]

You can think of it like taking a letter and wrapping it in envelopes, with each envelope containing addressing information. First it gets wrapped in a TCP or UDP envelope, then that gets wrapped in an IP envelope, then THAT gets wrapped in an Ethernet or WiFi envelope, and then that gets passed to your mail courier.

[@BurgerKingHarkinian]

Much better visual representation of what's actually going on imho

[@SWinxyTheCat]

Wow. This makes *so much sense* now. I feel... enlightened!

[@HoshiFanatic]

I recommend Network+ Comptia cert for stuff like this.

[@ianthehunter3532]

You should've included 3:15 before you started explaining IPs. I was already about to comment you missed a layer xD

[@nakulchauhan6713]

[@harshgandhi100]

I like the "what to do with my hands" pose computers are idling on.

[@bopon4090]

This is a really good video about networking. ❤️

[@perryuploads776]

Exactly, if you are a hacker, learn and ask questions yourself how it works. If you understand the basics very well of the OSI and TCP/IP layers then everything will makes sense to you. Networking is an art. In reality, you can write code to interact to your TCP/IP driver in Windows using Windows Sockets API, that interacts with Network Driver Interface Specification (NDIS) , that interacts with your NIC driver. So many abstractions ;) Do not forget, there are more protocols then TCP/IP, before we had IPX/SPX. Novell used NetBEUI and Microsoft used NetBIOS for file sharing protocols like SMB. Hence, Novell had NDS (Novell Directory Services), but Microsoft (i think copied it ) and made AD (Active Directory), and since Windows 2000 the revolution had begun. Windows XP came alive. Ahh the times, yes I feel old.

[@Henry-sv3wv]

real hackers use linux because with windows all you see is black boxes (closed source)

[@SilkG]

[@uriumkotil6915]

Amazing Series! Great explanation, even newbies gon understand it. Keep it up :)

[@alexandersumczynski7477]

I love these kinds of videos, keep up the good work and I am excited for the next video😊

[@luigigaminglp]

Im at 2:30 and i have to note this: If you attach a regular switch to a few PCs (no Router Mentioned) and use the IP layer, you won't get far. You need the MAC-Adress instead. Im pretty sure this gets cleared up soonafter, but at that very moment thats just not true.

[@luigigaminglp]

My solution would be to explain the MAC-Adress (and 2nd layer) briefly, and then attaching a single Router to the model and explaining IP then.

[@foundfpvfootage]

This is a great explanation. I am sad you didn't include the layer 2, but rather focused on the "more important" Layer 1 and 3 :/ The video is very well done regardless, thank you!

[@justcurious1940]

I think understanding the operating system part and the application part of the OSI model is crucial to fully picture and understand how data is being exchanged.
