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

because he really understands it xD
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.

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 ?

@@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.

Man, he should go deeper and wider with a complete tutorial on Computer Networks academic level!
Please make more (Deepdive) videos! They Are great and very informative
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
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.
You're warming up to me, Finally Explaining stuff without a passive Condescending Tone , Amazingly Done 👍🏾
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)
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!
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.
This series is proving to be the one is always wished for.
Man you make this so fun and easy to digest with the supportive visuals
This deepdive series is invaluable....please keep doing this
Great explanation!!! Please make more such videos on other networking basic concepts Cheers!
You made the server concept "click" for me. please continue this deepdive series as more topics need to be unraveled like this
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.
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...
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 :)
Thank you so much for this video. Much needed one for me. Please continue this deepdive as a series.
Amazing video, the way you explain things is the best. Please make more videos deepdive like this.
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).

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.
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.

Anyone who goes through the time to read and implement those protocols (by reading the RFCs) are.... mad lads
I love the deepdive series so much! I never knew about protocol this far!
This video is really crazy, clearly explained everything with examples
Love this series. More of anything please!
This is what i am searching for since 3 months thank you
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 :)
I love this format! Awesome video dude 🤙
Amazing video, I didn't really learn anything new, but your "style" of explaining things is really good.
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!
Great video as always. I've often found the concept of protocols a bit enigmatic but this was really helpful!
I have been watching KZread for a better part of my life and his video's 15 sec intro just made me subscribe love the honesty and motivation.
Another great explanation!. Kindly make a deep-dive video on OSI Model.
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
Thank u for the informative video! It really helps me to understand what is protocol.
You are a gifted teacher. Period.
Thanks for the good video. It cleared many of my doubts.
This video is the answer to my search for the question for so long!
Thanks! I love figuring out exactly how things work and this really helped me with that!
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.
More Deepdive please. Amazing content!
I love how you have explained the Protocols
Yep, That's what I was looking for !!! Awesome work
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
a video that i wish existed back when I was learning protocols, great job !!
This video was amazing! I took lots of notes from it, you're inspiring!
Very detail but easy to understand video! Thanks
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.
This is the best explanation I've seen about this topic! Good stuff man
finally! it's all begining to make sense! thank you :)
Such a great explanation! Just...thanks!
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.
i think you're gonna finally taught me what networking is all about. I bet your 17 year old self is grateful to you!!!
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.
Awesome Video! Thanks for explaining it👍🏻
This was a REALLY amazing video, just fantastic
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!
Thank you for the video, really clear !
You have the best explanation skills! Thank you for this!! :)
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.
❤the best explanation I have encountered! Thanks ❤
You are so much more helpfull than my teacher.
These Deepdive videos are awesome keep them coming :)
This is amazing as a web developer I'm very grateful for explaining it so well for me!
extremely well explained!
your hardworking must be appreciate!
Excellent video, superb, thank you
Great video,love it . Would love to see a video about certificates and their working
please never stop making such videos
Danke für die Erklärung. Frohes Fest und Guten Rutsch 🎊🎆🎈
thank you so much bro this series is fireeeee
wow best video about protocols ive ever seen
Amazing Explations thanks for this.
Great content, thank you for this explainer.
Thank you im in the industry and this is refreshing.
Thank you for this awsome explanation. Looking forward to more of these videos from you.
Thanks this was super helpful!
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 ✌️😎💕
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.
Incredible work 👏
Your videos are pure gold :)
Wow! Dude. You think exact the same way that I think and I was wondering about such things. I really wanted to get what they really means. Now I get it. Thank you!
Great video! Thank you!
the tcp explation was great
man.... you are awesome!! thanks by sharing the knowledge!!
Please continue with this series
Great Video! :D Another interesting topic for a video would be the OSI Model.
What an amazing video!
I would be very happy if you made more videos like this.
Thanks for the video!
Amazing explaination sir ! Really helpfull for a freshman like me
Man, you are THE best!
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!
😍😍😍😍 your explanation is too good man really appreciate how you tell everything 👍👍👍🤩
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 :^)
Hell yes just the video I needed
Trank you so much, helped me relate http with (until yesterday completely unrelated in my Head) UCI or CECP, the Chess engines protocol for communicating with an end User and with another
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
Perfect explanation!!! Please make videos about SMB or LDAP
Great video man.
