The document outlines three models of communication: 1) The linear model involves a one-way transmission of messages from a sender to a receiver with no feedback. It is used in mass communication like television and newspapers. 2) The interactive model allows for feedback as the receiver can encode and send a response to the original sender. It describes interactions like text messages and phone calls. 3) The transactional model depicts face-to-face interactions where senders and receivers can take on both roles simultaneously, resulting in messages being exchanged back and forth. It is a more dynamic process where the success of communication is unclear.
