![]() So how does TFTP work then? A TFTP server is always on call at port 69 for any incoming requests from the TFP client. This is due to the fact that the TFTP server needs to divide data into pieces when transferring it to the TFTP client. Unlike FTP, TFTP is slower in its transferring process. As a user, you only need to know the file’s name you’re trying to download, and you can send a command to request that specific file. TFTP does not need to authenticate a user. Hence, if you want to access an FTP server, you should verify yourself with a username and password. So if you send a file using UDP, your computer will not care if the information is received or not on the other end.įTP uses ports 21 and 20, whereas TFTP uses port 69.įurthermore, FTP requires a password to authenticate the user. Hence, unlike TCP, it does not verify a connection between the two computers to guarantee that data is delivered correctly. UDP, on the other hand, is connectionless. TCP verifies the connection between the two computers before any communication can take place between the computers. TCP guarantees that you receive all your data correctly. For example, if you’re downloading a file, you want the entire file and not just parts of the file. Whenever a file is transferred to your computer from another computer, your data needs to be received correctly. The communication between computers needs to be secure and reliable. ![]() Since TFTP uses UDP instead of TCP, it’s an unreliable transfer protocol. TFTP relies on UDP (User Datagram Protocol) as it is a connectionless protocol. FTP relies on TCP (Transmission Control Protocol) during transport. ![]() The difference between TFTP and FTP lies in the mechanism. What is the difference between TFTP and FTP?
