Question

which statement is true about ftp?
ftp does not provide reliability during data transmission.
ftp is a peer - to - peer application.
the client can download data from or upload data to the server.
the client can choose if ftp is going to establish one or two connections with the server.

Explanation:

FTP (File Transfer Protocol) is a client - server protocol. The client - server model means there is a clear distinction between the client (requesting data or services) and the server (providing data or services), so it is not a peer - to - peer application. FTP uses TCP (Transmission Control Protocol) which provides reliable data transmission. FTP always establishes two connections with the server: a control connection and a data connection. One of the main functions of FTP is that the client can download data from the server (retrieve files) or upload data to the server (store files).

Answer:

The client can download data from or upload data to the server.
