There is absolutely longer latency using TCP as the process does not proceed forward without receiving the next packet.
We're talking real world, internet, not your private lans or internal corp networks.
You did exactly what I thought you would, you tried to get exceptionally technical with ambiguous technical statements about TCP vs UDP.
You are correct that in an environment with no other traffic, UDP and TCP transmission would not introduce additional latency. I wouldn't want to be hired
by someone who couldn't handle real world concepts, you sound like like potentially a middle manager that has no idea of real world concepts.
So I'll explain it. Why would TCP have a higher latency over the internet? As you don't control the network, you also cannot ensure the quality of the networks you are routed through. This means when packets are dropped, you wait to receive another packet, as it sends the packet again In most voice conversations, this causes a delay as it buffers communications before playing them on your end. E.G receives enough packets.
When using UDP it sends the packets without waiting for an acknowledgement of the receipt of the packets, therefore when transmitting packets and some get lost, you lose a little voice quality or get the odd artifact.
Alternatively, you could use TCP, and adjust the buffers so that it doesn't wait for the person transmitting to stop talking before sending the information. If it all reaches there with no problem, no issue, if packets are dropped a long the way, you will get artifacts and jitter.
So yes, adjusting the buffers makes a difference, but can also increase latency in environments where you do not control the internet and travel fair distances network wise.
So the reality is, you're an idiot that's omitting fine details to try to make yourself look correct. This is akin to someone who preys on those less knowledgeable managers to make their co-workers look bad by spouting information that is correct in specific situations, but doesn't apply to what is actually being discussed.
It's a terrible practice, if you know anything about networking at all or are in a position where you can decide if someone is an expert or not, you would know that the scenarios I've described are accurate.
Obviously your natural defense is a strong offense, point out other peoples flaws and discussed things like trying to distract, which is entirely what you're doing. It's called projecting. If you weren't doing it, you wouldn't have put the first post you did.
Now, I don't need to convince anyone reading it's right, as they know it is, which is why they're not commenting, as they're more mature than I am and I shouldn't have responded in the first place. As for insulting you, well, yes I did. I do apologize for it, but even with that, I'm not removing it from this post either, as you're being an idiot.
