Why TCP is better than UDP ?

TCP is reliable and connection oriented why that's why tcp better then UDP.

TCP is more reliable than UDP, and has acknowledgement segments. Also has guarantee that the order of data receiving same as on sending   

TCP:  reliable it guarantees the delivery packets uncorrupted, Connection Oriented in a way that data travel both ways, guarantees that packets arrive in order unlike UDP which contradicts everything mentioned before, it does not guarantee delivery of packets, Connectionless, and packets can be delivered out of order

TCP is a connection oriented protocol whereas UDP is connection less. TCP guarantees packet transmission whereas UDP doesn't

TCP is better than UDP because sender receives acknowledgement from receiver at the time of connection establishment, so no packet loss occurs.

TCP is reliable then UDP beacuse TCP got acknowledgment on packet transfer.
