The Trivial File Transfer
Protocol (TFTP) allows a local host to obtain files from a remote host but does
not provide reliability or security. It uses the fundamental packet delivery
services offered by UDP.
The File Transfer Protocol (FTP) is
the standard mechanism provided by TCP / IP for copying a file from one host to
another. It uses the services offer by TCP and so is reliable and secure. It
establishes two connections (virtual circuits) between the hosts, one for data
transfer and another for control information.
