implemented on the basis of UDP.
TFTP transmission is originated from the client end. To download a file, the client
sends a request to the TFTP server and then receives data from it and sends an
acknowledgement to it. To upload a file, the client sends a request to the TFTP
server and then transmits data to it and receives the acknowledgement from it.
TFTP transmits files in two modes: binary mode for program files and ASCII mode
for text files.
