Varun sir explains UDP (User Datagram Protocol) header here.

UDP uses headers when packaging message data to transfer over network connections. UDP headers contain a set of parameters called fields.
The User Datagram Protocol header has four fields, each of which is 2 bytes. They are the following:

Source port number, which is the number of the sender;
Destination port number, the port to which the datagram is addressed;
Length, the length in bytes of the UDP header and any encapsulated data; and
Checksum, which is used in error checking -- its use is required in IPv6 and optional in IPv4.

0:23 - Connection Less
2:27 - Unreliable
2:49 - No ordering
3:17 - Source Port and Destination Port
4:49 - Length
7:27 - Checksum
