  <a href="https://www.youtube.com/watch?v=Y2mDwW2pMv4&amp;t=800">13:20</a> Is this overhead inherently caused by the syscall approach ?<br>I mean, if you go the &quot;shared memory&quot; route, you&apos;d have to essentially re-implement the synchronizing behaviour of the kernel&apos;s messaging implementation anyway.<br>Would there still be a significant increase in performance even after doing that ?

  The most unanswered or confused part to this date was ports, sockets and pipes.<br>I had given up searching on this topic. But accidentally hit this video and the moment I heard the word pipes, sockets, and port, all my brain cells made a permanent communication path.<br>Thanks, &nbsp;so many years of confusion cleared in a minute.

  This is hands down one of the best channels on YouTube. Thank you so much for all the work you put in.

  <a href="https://www.youtube.com/watch?v=Y2mDwW2pMv4&amp;t=745">12:25</a> - You have no idea how much I needed this.<br><br>I mean, I do understand—the server and client are essentially processes on their respective machines. I&apos;ve even written simple programs and worked with interconnected systems, so you&apos;d think I would have an intuitive grasp of it.<br><br>But the way it’s often represented, with the client and server depicted as entire machines, really stuck with me, and I couldn’t separate them in my mind. This explanation feels like a breakthrough. I think it’s going to help me develop a much stronger intuition about how OSes and IPC work. Thank you.

  I swear Core Dumped is like a leaker from the dev community. All the devs obfuscate their knowledge and yet Core Dumped is like a prophet!!!

  <a href="https://www.youtube.com/watch?v=Y2mDwW2pMv4&amp;t=742">12:22</a> Wow. This was such a good explanation, it actually made something click so well in my head, it&apos;s insane!<br>I discovered your channel about a month ago, and ever since have been watching your videos (first the computer architecture series, and now this operating system series). I though already knew about most the topics discussed, but at a very very basic level, because even though program and code frequently, I don&apos;t have a lot of education in the more fundamental theory dealing with low level programming. Your videos are actually such a good resource, and I actually retain the knowledge back to the first video I watch of yours.<br>I&apos;ve known about client-server architecture, of course, but never understood why a server and a client on the same machine are refered to that way, and what exactly does the &quot;port&quot; in the IP address mean. This explanation cleared it up so well. Thank you!

  Jetbrains sponsorship is deserved for all this hardwork

  for years I been trying to understand ports. This video was godsend. Please continue on this series and provide more information on networking from operating system POV
