Correct option is B
The correct answer is (b) File Transfer Protocol
Explaination:
· FTP is a standard communication protocol used to transfer computer files from a server to a client on a computer network.
· It is built on a client-server model architecture using separate control and data connections between the client and the server.
· Users can authenticate themselves with a clear-text sign-in protocol, normally in the form of a username and password, though they can connect anonymously if the server allows.
Information Booster:
· FTP typically uses Port 21 for the command channel and Port 20 for the data channel.
· Because standard FTP transmits data in plain text (including passwords), secure versions like SFTP (SSH File Transfer Protocol) or FTPS (FTP over SSL) are preferred for sensitive data.
Additional Knowledge:
· File Type Protocol: This is not a standard networking term; file types are generally identified by extensions or MIME types rather than a specific protocol.
· File Telnet Protocol: Telnet is a separate protocol used for providing a bidirectional interactive text-oriented communication facility; it is used for remote login, not specifically for file transfer.
· File Transit Protocol: This is a fictitious term; while "transit" refers to movement, the industry-standard technical term is "transfer."
