How TCP and UDP packets come to the world

You got that baby? Great, I'll send the next 500 much faster, tell me when you drop one and I'll slow down again.

No. Both UDP and TCP can be intercepted the same. The difference is that UDP sends a packet to an address. But doesn't have any in built system to check that it arrived, that it arrived intact or to resend if it didn't. There's also no built in way to protect against spoofing or out of order packet delivery. But generally implementations will handle the ones that are important of those themselves.

TCP establishes a circuit, packets are sent, verified and resent if required until the original data, in the correct order is delivered to the application. Also there is some protection against spoofing with sequence numbering. The downside is that time sensitive data might be delayed because of the retransmission and re-assembling. Which is why time sensitive streams like VoIP are usually sent over UDP.

No. UDP is at the packet level. Interception is a different layer.

To use to today's language, UDP yeets the packets at you as fast as it can generate them.

It doesn't care if you catch any of them.

Don't yeet the baby.

It's not so much that anyone can intercept it, it's more that the sender just blasts it and no acknowledgement so there's lots of potential for loss

The benefit is that you don't need to wait for verification from the user that they got the packet before you can send the next group of packets. If you're, say, watching a stream, it's not important that you received the packets because that's just a few skipped frames or a second of lag, whereas the tradeoff on overhead is pretty big.

TCP is more important with like file downloads where it's okay if it takes a couple hours to get a really big file as long as that file isn't corrupted or missing any data.

You'd have to be somewhere in the route from A to B to intercept it. But TCP is no different in that regard.

TCP is connection based so both sides need to agree to connect before data is exchanged. UDP is connectionless, so it will send data from A to B (and vice versa) regardless of if the other side is available.

From what I can tell yes. There's no established connection, the data is sort of just broadcasted.

Edit: I was operating under a misunderstanding, please refer to andrew's response.

No, instead of using TLS for encryption (like most TCP traffic) UDP will use things like DTLS and SIP

Or if you're asking about the actual transport it's more like TCP is going to your friend's house and calling your mom to let her know you're there vs UDP is going to their house and not calling.

"not get You" Don't forget the packet loss and non-ordered packets.

Please stop.

In a world where there is racism, acting like racist themes don't exist only helps prolong it.

One set of of people here was drawn white (and responsible with a child), the other was drawn black (and irresponsible). That's worth critiquing, intentional or not.

Acting racist doesn't mean you are literally Satan, it means you are acting racist. Not stopping after people point it out and acting defensive and in denial is worse than thoughtlessly doing something racist, being told off and then correcting
