Note to add: Why does UDP even have checksum for "error detection" if it doesn't do any "error recovery"? - Error recovery is when we retransmit because we have detected error - Error detection is when we simply check for an error Textbook states: "Although UDP provides error checking, it does not do anything to recover from an error. Some implementations of UDP simply discard the damaged segment; others pass the damaged segment to the application with a warning" - Computer Networking: A top-down approach Kurose, Ross Note #2: So why should we ever use UDP? - When timing is more important and little loss of data does not matter too much - For example, Online Live Meetings (e.g. like zoom or skype). Timing is more important than a few frames of the video not showing properly or a few words not heard by the listener (speaker can just repeat the word simply). At these points we actually don't even want to retransmit to recover the error (lost/glitched frames of video or miliseconds of glitched/lost sound). Because the moment these data mattered has already passed. However we want our online meeting to be as much as like a real meeting minimising delays, so timing is important. Hence we should use UDP.

Still quantifiable and less than infinity. So, I don't love you, you don't love me.
