FTP and TFTP are primarily file transfer protocols. What is the main difference between both.
Solution
FTP stands for File Transfer Protocol. It is used to send/receive file from the remote computer. It
is defined in RFC959. FTP establishes two connections between client system and server system,
one for control information and the other for data to be transfered. Control information carry
commands/response. Authentication need to be done initially by way of validating username and
password. Once it is done files can be transferred between two systems. FTP handles both binary
and text format files.
When a FTP client requests to connect to the FTP server, a TCP connection is being established
to the FTP server\'s port 21 reserved for FTP. After authentication is done, another TCP
connection is being established for the actual data transfer on port number 20.
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.
As TFTP is unreliable protocol due to UDP, it uses application layer recovery supported by
UDP. This is done by embedding a small header between the UDP header and the data. This
header incorporates codes for example read,write and acknowledgement along with numbering
scheme which numbers 512 bytes of data. These block numbers provided are used to
acknowledge the receipt and re-send the data in case of checksum failures. TFTP sends one
block and waits on acknowledgement before sending another block.
