The document discusses the communication process, which involves a sender encoding a message and sending it through a channel to a receiver. The receiver then decodes the message and can provide feedback to the sender. Specifically, it defines the sender as the person who sends the message, encoding as how the sender logically arranges their idea into codes, the channel as how the message is conveyed, decoding as how the receiver translates the words into meaning, the receiver as the person who gets the message, and feedback as the receiver's response.
