The document discusses two classic models of communication: Aristotle's model and Lasswell's model. Aristotle's model from ancient Greece is one of the earliest and most widely accepted models, focusing on a speaker delivering a message to an audience with the goal of producing a certain effect. Lasswell's model from the 20th century proposes analyzing any communication act by answering who says what through which channel to whom with what effect. Both models are examples of one-way communication and lack feedback. They were important early contributions to understanding communication but have limitations like not accounting for noise or the potential for communication to fail.
