The Shannon-Weaver model, developed by Claude Shannon and Warren Weaver in 1948, is a foundational framework for understanding communication. It describes the process of transmitting information from a sender to a receiver through a channel, highlighting key components such as the sender, message, encoder, channel, decoder, and receiver. This model also introduces the concept of noise, which refers to any interference that can distort the message during transmission. By identifying these elements, the Shannon-Weaver model helps analyze and improve communication effectiveness in various fields, including telecommunications and information theory.
