Hi,
We know that UDP does not contain any acknowledgement mechanism. But the TFTP which uses UDP sends the ACK packet on reception of data packet. How is this justified?

And if the TFTP is sending the ACK packets, the overhead is bound to happen so why not use TCP instead? What makes TCP not usable for file transfers?
