Can you use UDP and still get the advantages of TCP by some way?

That depends on the protocols used. TCP provides reliability, but if TCP is not used, higher-level protocols can include the reliability instead. That is to say, if a packet is not received, the higher-level protocol will take the responsibility of sending (or requesting) the packet again.For example, TFTP (Trivial File Transfer Protocol) uses UDP, and automatically resends a packet when an acknowledgement is not received after a certain time.That depends on the protocols used.
