The differences between FTP and TFTP

The differences are :

FTP is a complete, session-oriented, general purpose file transfer protocol.
TFTP is used as a bare-bones special purpose file transfer protocol.
FTP can be used interactively. TFTP allows only unidirectional transfer of files.
FTP depends on TCP, is connection oriented, and provides reliable control. 
TFTP depends on UDP, requires less overhead, and provides virtually no control.
FTP provides user authentication. TFTP does not.
FTP uses well-known TCP port numbers: 20 for data and 21 for connection dialog. 
TFTP operates at UDP port number 69 for its file transfer activity.
The Windows NT FTP server service does not support TFTP because TFTP does not support any authentication.Windows 95 and TCP/IP-32 for Windows for Workgroups do not include a TFTP client program.
