Difference Between FTP and TFTP

These systems need to be connected to an IP based network. Both the term, FTP and TFTP, are often confused for one another due to their somewhat similar abbreviations.


The main difference between FTP and TFTP is that FTP has a wide variety of instructions and commands that can be used for specific purposes whereas TFTP has only five commands which include Write Request (WRQ), Read Request (RRQ), Acknowledgement (ACK), Data (DATA), and Error (ERROR). Moreover, FTP is a very complex protocol whereas TFTP is not as complex as the former.


The full form of FTP is File Transfer Protocol. This is a standard application protocol that transfers or copies a file between two hosts. It works on two ports – 20, which is for data, and 21, which is for connection control.

The full form of TFTP is Trivial File Transfer Protocol. The protocol transfers a file from a host to a client and vice versa. This is done without the use of the FTP feature.

What is FTP?

FTP is a standard application protocol that is used for communication on a computer network. This involves transferring files from a host to a client and vice versa.

The software also encrypts itself with FTPS frequently or replaces itself with SSH File Transfer Protocol. This results in all kinds of security threats being removed and minimizes the risk of security breaches. 

Originally, the specification for FTP was written by Abhay Bhushan. It was published on 16 April 1971 as RFC 114. For many years, the software ran on NCP.

Now, FTP can run in active or passive mode. This determines how the connection between two hosts will be established. By carrying out either of the two kinds of processes, the host creates a control connection between two ports.

What is TFTP?

TFTP is a simple communication protocol that allows the transfer of files to and from random hosts and clients. It is very useful when a node is being booted from a local area network.

TFTP can also be used to transfer firmware images and configuration files to various network appliances. These include firewalls, IP phones, routers and much more.

The design of TFTP was derived from EFTP, which was an earlier protocol. It was even a part of the PARC Universal Packet protocol suite. The software came to be defined only in 1980.

However, a limitation of using TFTP is that it poses certain security risks. The software does not have a username and password; thus, it requires no authentication for login.

Main Differences Between FTP and TFTP

  1. FTP provides a secure channel for file transfers whereas TFTP does not.
  2. FTP is useful for uploading and downloading files by remote users whereas TFTP is useful for configuration transfer between network devices.


FTP and TFTP are both used for file transfers. While FTP is large in size and uses up more memory space, TFTP is relatively smaller and does not use as much memory space as the former.

On the other hand, FTP does not require a login for use. This increases the risk of security threats and breaches.
