FTP vs. SMTP: Know the Difference
By Shumaila Saeed || Published on February 1, 2024
FTP (File Transfer Protocol) facilitates file transfer between computers, while SMTP (Simple Mail Transfer Protocol) is used for sending emails across networks.
Key Differences
FTP, or File Transfer Protocol, is a standard network protocol used for transferring files from one host to another over a TCP-based network, such as the Internet. SMTP, or Simple Mail Transfer Protocol, is a protocol used for sending email messages between servers.

FTP operates by opening two connections between hosts: a command (control) connection and a data connection. SMTP, however, communicates over a single connection, using a series of text commands to send email between servers.

In terms of security, FTP has variants like FTPS (FTP Secure) that provides encryption for file transfers. SMTP also has a secure version, SMTPS, and can use extensions like STARTTLS to provide secure email transmission.

For user authentication, FTP typically requires a username and password to access files on a server. SMTP, on the other hand, does not necessarily require authentication by the sender but focuses on the transmission and routing of emails.
