Why does YouTube use TCP instead of UDP?
3 Answers. Because they need everything TCP provides (slow start, transmit pacing, exponential backoff, receive windows, reordering, duplicate rejection, and so on) they would either have to use TCP or try to do all those things themselves.
Does YouTube video use TCP or UDP?
Youtube uses TCP to control messages rather than UDP because of many reason If we use UDP we might get better performance than TCP but UDP will loose many chunks of packet while streaming due to the lossy nature of Internet communications .
Why is TCP used over UDP?

Why does Netflix use TCP and not UDP for its streaming video?

Why is TCP used for video streaming?
Transmission Control Protocol (TCP) TCP was designed to offer a highly reliable, end-to-end byte stream over an unreliable network. It “cares” about the quality of the data stream and prioritizes an ordered, reliable delivery of packets.
Does live streaming use TCP or UDP?
Undoubtedly for live video sharing, UDP (User Data Protocol) is always recommended over TCP (Transport Control Protocol) due to some of the obvious reasons which are listed as below: UDP offers reduced latency over the TCP reliability.
Which two operations are provided by TCP but not by UDP detail and explanation briefly about two of them?
TCP uses handshake protocol like SYN, SYN-ACK, ACK while UDP uses no handshake protocols. TCP does error checking and also makes error recovery, on the other hand, UDP performs error checking, but it discards erroneous packets. TCP has acknowledgment segments, but UDP does not have any acknowledgment segment.
