Encoding ensures the message is put into a symbolic form (such as words, sounds, or gestures).
It is the first step in the communication process, where the sender transforms the message into a format suitable for delivery.
Transmission is the process of sending the encoded message from the sender to the receiver.
Decoding is the process of interpreting the encoded message by the receiver, converting it back into a format they understand.
Treatment refers to the way a message is handled or processed after encoding.
