- TCP is more reliable than UDP because it requires lost packets to be retransmitted.
- TCP requires less processing by the source and destination hosts than UDP.
- UDP introduces delays that degrade the quality of the data applications.
- TCP ensures fast delivery because it does not require sequencing or acknowlegements.
