Final answer:
Public communication is defined as the use of messages to create meanings in a mediated system between a source and a large, unseen audience, facilitated by mass media like TV, radio, and the Internet.

Step-by-step explanation:
Definition of Public Communication
Public communication is best defined as the process of using messages to generate meanings in a mediated system, between a source and a large number of unseen receivers. This form of communication utilizes various forms of mass media, including television, radio, and the Internet, to convey messages to a broad audience. Unlike two-person communication or small group interactions, public communication is characterized by its one-to-many dynamic, where one entity (whether an individual, an organization, or a government body) transmits information to many people simultaneously. Mass media plays a crucial role in this process by acting as the conduit through which the message is disseminated, ensuring that the content can reach a large number of individuals across diverse geographical areas.
Understanding public communication is essential as it fulfills the role of being the Common Carrier, providing a crucial link between the government and the public, and vice versa. In today's society, technology's rapid advancement has heavily influenced the way public communication is conducted, with a shift towards new media that relies heavily on electronic technology and the Internet. Crucially, the medium through which the message is transmitted can significantly shape the content and the experience of the audience, as famously noted by media scholar Marshall McLuhan with his aphorism "the medium is the message".
