FTP vs. SMTP: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on February 3, 2024
FTP (File Transfer Protocol) is used for transferring files over a network, while SMTP (Simple Mail Transfer Protocol) is used for sending emails.
Key Differences
FTP, or File Transfer Protocol, is a standard network protocol used for transferring computer files between a client and server on a computer network. SMTP, or Simple Mail Transfer Protocol, on the other hand, is a protocol used for sending emails from one server to another.
FTP operates on a client-server model and uses separate control and data connections between the client and server. SMTP, however, operates on a server-to-server model, primarily used for sending and forwarding emails.
FTP can transfer various types of files including text, binary, or multimedia files. SMTP is specifically designed for sending text-based messages (emails), not for file transfer.
In FTP, users can upload, download, rename, move, or delete files on a server. SMTP does not interact with files on a server; it simply transmits email messages to the recipient's mail server.
FTP requires authentication (username and password) for accessing files on a server, ensuring a secure transfer. SMTP also uses authentication but focuses on ensuring that emails are reliably and securely delivered.
