UDP

How does UDP work?

The UDP protocol works by immediately firing data at the receiver who made a data transmission request, until the transmission is complete or terminated. Sometimes called a “fire-and-forget” protocol, UDP fires data at a recipient in no particular sequence, without confirming delivery or checking if packets arrived as intended.

While TCP establishes a formal connection via its “handshake” agreement before sending data. UDP doesn’t have time for that. It speeds up data transfer by sending packets without making any agreement with a receiver. Then, it’s up to the recipient to make sense of the data.
