SFTP, or Secure File Transfer Protocol, is specifically designed to provide secure file transfers over a network. It operates over the Secure Shell (SSH) protocol, which encrypts the data being transmitted, ensuring that both the commands and the data are secure from eavesdropping or interception. This security feature distinguishes SFTP from other file transfer protocols that may not provide encryption or have robust security measures.

The definition of SFTP as a secure method for file sending using SSH highlights its primary function and the technology it relies on for secure communication. This is crucial in environments where sensitive data is transferred, and protecting that data against unauthorized access is paramount.

Other options focus on different characteristics or uses:

- The first option describes a generic file sending protocol without security, which does not apply to SFTP since security is a core feature.

- The third option mentions real-time data streaming, which is unrelated to the primary purpose of SFTP, as it is not designed for real-time transfers but rather for securely transferring files.

- The fourth option refers to a protocol designed solely for multimedia files, which again does not fit SFTP's purpose or functionality, as it is suitable for transferring a wide array of file types, not limited to multimedia.
