This means the communicated messages are also well-defined. Besides, the protocol can also include possible error recovery methods.

The protocol can be implemented by either software or hardware.

Answer 2

Answer:

iii. File Transfer Protocol (FTP) for data and file transfer services between a client and a server on a network.
