UDP: It is a connection-oriented protocol. It is a connectionless protocol. TCP reads data as streams of bytes, and the message is transmitted to segment boundaries.

What are the drawbacks of using UDP protocol?
Here are the cons/drawbacks of UDP: In UDP protocol, a packet may not be delivered or delivered twice. It may be delivered out of order, so you get no indication.
