Solution

Transport layer protocols are used for end-to-end communication between applications.

TCP is a connection-oriented transport layer protocol.

It establishes a connection before data transfer.

UDP is a connectionless transport layer protocol.

It does not establish a connection before sending data.

UDP sends data in the form of datagrams and is part of the Internet protocol family.

Routing Protocol works at the network layer.

Datagram Control Protocol is not the standard connectionless transport protocol in the TCP/IP family.
