Explanation:
Detailed explanation-1: -TFTP is a simple protocol for transferring files, implemented on top of the UDP/IP protocols using well-known port number 69. TFTP was designed to be small and easy to implement, and therefore it lacks most of the advanced features offered by more robust file transfer protocols.
Detailed explanation-2: -As mentioned, TFTP uses UDP as a transport, as opposed to TCP which FTP uses, and works on port 69, you can clearly see that in the cool 3D diagram on the left. Port 69 is the default port for TFTP, but if you like, you can modify the settings on your TFTP server so it runs on a different port.
Detailed explanation-3: -UDP/69-The TFTP server uses this port for TFTP transfers.
