  Great. Silent downvotes from HNers that don't even know TCP.

    1) They're formative knowledge for understanding that part of a system. Systems are big and few people understand them entirely. I happened to know those things, but I am a pathologically T-shaped/"paint drip" developer. The middlebrow dismissal of "oh that's basic" is going to get a rise out of people. 2) You threw a one-line, no-help comment out there. That's going to get you downvoted unless it is at least interesting or funny. 3) Now you're complaining about downvotes, which is a big red sign for "downvote me more, for I am mad".
