    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 ?

    • @Miles-co5xm
      @Miles-co5xm 2 ปีที่แล้ว +4

      @@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.

    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 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.

    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.

  • @mingxingchen3797
    @mingxingchen3797 2 ปีที่แล้ว

    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.

  • @OhMyJawsh
    @OhMyJawsh 2 ปีที่แล้ว +15

    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)

    • @GeorgeValkov
      @GeorgeValkov 2 ปีที่แล้ว +3

      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.

    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

    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.

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.

    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.

    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.
