Protocols specified in the TCP/IP standards Architecture.

Full Answer Section

Implementation: FTP works by establishing two separate connections:

1. Control Connection: This dedicated connection is used for sending commands and responses between the client and server. Commands specify actions like login, list files, upload, or download. Responses confirm success or report errors.
2. Data Connection: This temporary connection handles the actual transfer of file data. Once the control connection negotiates the transfer, the data connection opens, sends the file, then closes. This separation keeps the control channel free for ongoing communication while data transfer occurs efficiently.

By utilizing separate connections and a command-response structure, FTP ensures reliable and controlled file transfer over networks.
