UDP does not perform any of the handshaking sequences that are seen with TCP. UDP is a lot less reliable than TCP, but UDP does offer more speed than TCP. This is ideal for data that does not require all packets to arrive and in order and needs fast delivery. Such services that use UDP are ones like DHCP and DNS. This protocol is the easier of the two protocols of TCP/IP to spoof since it does not use sequencing or acknowledgement numbers.
