Network - User Datagram (UDP)


UDP is a User Datagram Protocol

It establishes connections that are:

It emphasizes reduced latency over reliability. For a reliable data stream, see TCP.

UDP is connectionless. See UDP - (Datagram|Connectionless) Socket (Endpoint)

It improves the latency by enabling the transfer of data before an agreement is provided by the receiving party.

The U implies less reliable data transmission than TCP connections.

You may have trouble sending large amounts of data that way, but it's still a useful capability to have.
