Data is sent without errors or duplication and is received in the same order as it is sent. It groups the bytes in tcp segments and then passes them to ip. Data sent using a tcp protocol is guaranteed to be delivered to the receiver. On the other hand, udp is more efficient once the connection is established.
Tcp is connection oriented protocol, hence a connection need to be established using 3way handshaking before data is transmitted using tcp.

Udp is designed for applications where you dont need to put sequences of packets together.
Tcp is highly reliable for transferring useful data as it takes the acknowledgement of information sent. Tcp is a transmission control protocol and udp is a user datagram protocol. Udp is a simpler, connectionless internet protocol. It operates at a higher level than its compatriot, internet protocol also known as ip.
It is an unreliable and connection less protocol which is offered for services that require fast transmission of data. The most common alternative is udp user datagram protocol. Udp is connection less while tcp is connectionoriented which requires the latter protocol to establish full connection between the receiver and the sender. Udp is known as a connectionless protocol, and is simpler than tcpip. What is igmpinternet group management protocol most visited in difference between.

Both tcp and udp work at transport layer tcpip model and both have very different usage. On the other hand, udp stands for user datagram protocol. When you send a message using udp internet protocol, it is not guaranteed if it will reach the destination or get lost in between the transmission. This means that the data transmission is done without warning the recipient the machine b, and the recipient receives the data without making an acknowledgment to the transmitter the machine a.
The header contains 10 fields that must exist and an optional extension field. The new protocol can transfer data at a much higher speed than tcp does.
