This document discusses two models of communication: the linear model and the transactional model. The linear model, developed by Shannon and Weaver in 1948, describes communication as a one-way process where a sender transmits a message through a channel to a receiver. The transactional model views communication as an interactive two-way process with feedback between communicators who aim to understand each other. Learners are asked to identify the unique features of each model and which model best describes typical communication.
