Trivial File Transfer Protocol (TFTP) is a simple protocol for file transmission that has 
no complicated interactive access interface or authentication control, and 
therefore it can be used when there is no complicated interaction between the 
clients and server. 

TFTP transmission originates with the client. To download a file, the client sends a 
request to the TFTP server and receives the data, then sends an acknowledgement 
to it. To upload a file, the client sends a request to the TFTP server and transmits 
data to it, then receives the acknowledgement from it.
