The document summarizes two classic models of communication: Aristotle's model and Lasswell's model. Aristotle's model is one of the earliest and most widely accepted models, depicting a speaker-centered, one-way communication from the speaker to the audience. Lasswell's model provides a framework to describe any communication act by answering who says what through which channel to whom with what effect. Both models depict one-way communication without feedback and do not account for potential communication issues like noise.
