tcp is reliable than udp because it uses acks(Acknowledgment) but slower than udp because of acks.

Difference between UDP and TCP. UDP is much faster, used for streaming video and audio files on the net. TCP is slower, because it contains the main factor UDP does not have, which is flow/error control.
TCP is used by most users on the net because data transferred needs to be verified. Error correction allows data to be effectively received.
