  • 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@brucewayne2480 Жыл бұрын
    • @@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.

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.

    • 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.

  • 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)

  • 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

  • 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.
