The difference between TCP and UDP is connection(TCP) and connectionless(UDP) protocol.Because In TCP for transferring every Packets it needs a acknowledgement packet from reciever ,so if any packet loss happens reciver will not send a acknowledge ment for that packet so Transmitter will once again send the packet.so TCP is reliable connection unless UDP will send a packet and will not expect any acknowledgment from the reciever so it is not reliable.

TCP stands for Transmission control protocol and it is a connection oriented protocol. The sender will get acknowledged after recieving the packets successively, by the reciever. No other pacets were send till the acknowledgement from the reciever. Hence it is a reliable protocol.
UDP stands for user Datagram Protocol and it is a connectionless transport layer protocol. It allows applications to send encapsulated raw IP datagrams without establishing a connection To send one (or little data) reequest this protocol is used as there is no need to establish and then release the connection. UDP is an unreliable protocol compared to TCP.
