+UDP (User Datagram Protocol) is a lightweight [Network Protocol](/wiki/network_protocol) that sends individual data packets without establishing a connection. It offers speed over reliability, foregoing error-checking and retransmission found in [TCP](/wiki/tcp), making it a swift, fire-and-forget messenger.
