SMTP (Simple Mail Transfer Protocol) is a protocol used for sending emails, while FTP (File Transfer Protocol) is used for transferring files over the internet. The main differences are:
1. Purpose: SMTP is used for email transmission, while FTP is used for file transfers.
2. Port numbers: SMTP uses port 25 by default, while FTP uses ports 20 and 21.
3. Authentication: SMTP can perform limited authentication, while FTP allows more secure user authentication.
