Key Difference: TCP stands for transport control protocol. It is a connection oriented and reliable protocol and is used for transfer of crucial data. On the other hand, UDP stands for User Datagram Protocol. It is an unreliable and connection-less protocol which is used for services that require fast transmission of data.
UDP (User Datagram Protocol) is an alternative communications protocol to Transmission Control Protocol used primarily for establishing low-latency and loss tolerating connections between applications on the Internet. Both UDP and TCP run on top of the Internet Protocol (IP) and are sometimes referred to as UDP/IP or TCP/IP.
