All the data sent over TCP is tracked, and no data gets corrupted or lost on the way. The protocol numbers the packets and does error checking by pushing the receiver to confirm that it got the data.
This protocol is all about speed. All those checking of the packets slow down the communication and create latency. This makes it perfect for live streaming or online games, even if the connection stops for a bit and the screens of the receivers freeze, in a moment they will receive the next packet, and everything will continue.
The UDP just transmits the data and save plenty of time. UDP can support many more client at the same time thanks to the lack of connection state.

Or the same query might return the following TXT records, each providing a specific function such as spam detection or site verification as demonstrated in Figure FAQ In these situations, the client needs to re-transmit over TCP, which has no size limit.
The end symptom to the end client is usually slow DNS resolution, or inability to resolve certain domain names at all.
You might be wondering where the size limit of bytes come from. The IPv4 standard 2 specifies that every host must be able to reassemble packets of bytes or less, take away header and other options, that leaves bytes for payload data.
