FTP and TFTP :

FTP:

The File Transfer Protocol (FTP) is a standard network protocol used to transfer computer files from one host to another host over a TCP-based network, such as the Internet. FTP is built on a client-server architecture and uses separate control and data connections between the client and the server.

TFTP:

Trivial File Transfer Protocol (TFTP) is a simple, lock-step, File Transfer Protocol which allows a client to get from or put a file onto a remote host. One of its primary uses is in the early stages of nodes booting from a local area network.



 

Differences Between FTP and TFTP :

 Both of these protocols can be used for transferring files across the Internet. The differences between the two protocols are explained below:

• 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 uses UDP port number 69 for its file transfer activity.
