Answer:
UDP Port 69
<em>Trivial file transfer protocol (TFTP) operates over UDP port 69.</em>
Explanation:
UDP port 69 uses the Datagram Protocol, a communications protocol for the Internet network layer, transport layer, and session layer. This protocol when used over PORT 69 makes possible the transmission of a datagram message from one computer to an application running in another computer. UDP is used with <em>IP (the Internet Protocol)</em> and UDP Port 69 is <em>connectionless </em>which means it does not give reliable communication; it’s up to the application that received the message on Port 69 to process any errors and verify correct delivery.
