Trivial File Transfer Protocol (TFTP)
File-transfer-protocol uses TCP to get the communication in a reliable network. If the network is quite reliable, as is generally on the LAN can use a file-transfer-protocol that is more modest, namely to use the user-datagram-protocol (UDP) for the underlying transport protocol (host-to-host). As an example file that uses UDP-transferprotocol is trivial-file-transfer-protocol (TFTP).
Trivial File Transfer Protocol (TFTP) is a simple protocol to transfer files. It has been implemented on top of the User Datagram Protocol (UDP). TFTP is designed to be small and easy to implement, therefore, lacks most of the features of a regular FTP. TFTP only reads and writes files (or mail) from/to a remote server. It cannot list directories, and currently has no provisions for user authentication.
