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.

Hi,

TFTP (T for trivial) uses UDP and is more lightweight and has less features. It is a stripped down and simplified version of FTP.

FTP uses TCP, which means the receipt of packets is acknowledged and verified. Missing packets are requested to be resent. TCP is more reliable but FTP is not secure. There is no inherent security mechanisms present and anyone with a sniffer or the right software can grab the file as it goes by just as easily as the intended destination can.


Thanks.

TFTP stands for Trivial File Transfer Protocol. It is defined in RFC783. It is simpler than FTP, does file transfer between client and server process but does not provide user authentication and other useful features supported by FTP. TFTP uses UDP while FTP uses TCP.
