What is TCP vs UDP?

TCP is a connection-oriented protocol, whereas UDP is a connectionless protocol. The speed for TCP is slower while the speed of UDP is faster. … TCP does error checking and also makes error recovery, on the other hand, UDP performs error checking, but it discards erroneous packets.

Does twitch use UDP?

Is UDP secure?

The big security problem with UDP is that you are susceptible to spoofing and DOS attacks. It’s not possible to spoof an address across the internet using TCP since the handshake will never complete. OTOH with UDP there is no implicit handshake – any session maintenance must be done by your code (processing overhead).

What does UDP stand for?

User Datagram ProtocolUser Datagram Protocol (UDP) – a communications protocol that facilitates the exchange of messages between computing devices in a network. It’s an alternative to the transmission control protocol (TCP).
