UDP
|
User Datagram Protocol , UDP does not possess any of the extras that TCP uses to make sure the data is received intact. It works best when a lot of data must be sent that does not need to be perfect, or when the systems are so close to each other that the chances of a problem occurring are too small to bother worrying about. UDP is the "fire and forget" missile of the TCP/IP protocol suite. UDP is useful because it is significantly faster compared to TCP.
