It is determined by the program. UDP packets are normally used for video streaming. TCP is used where the data being transferred needs to be accurate

Both are Network layer Protocol. UDP packets do not follow dedicated path but TCP packet follow virtual dedicated path. So,UDP packets do not give guaranteed to reach destination but TCP give guarantee to reach destination. But we use UDP because they are faster than TCP.UDP does not have error handling mechanism and reverse acknowledgement. Because of all this reasons, We send E-mail through TCP and Live Streaming through UDP. In other word we say that,UDP packets acts as Postal office letters and of no assurance of delivery. TCP packets acts as Electronic mails and assurance of delivery.

Determined by the application program; UDP has no such overhead that TCP has; that overhead is for ensuring accuracy and receive of information.
