FTP VS TFTP

Summary:

1. FTP is a user-based password network protocol used to transfer data across a network; TFTP is a network protocol that does not have any authentication processes.

2. FTP may be accessed anonymously, but the amount of information transferred is limited; TFTP has no encryption process in place, and can only successfully transfer files that are not larger than one terabyte.
