In Shannon and Weaver's model of communication, what is the primary function of the 'encoder'?

The Correct answer is To convert the message into signals.

Key Points

• Shannon-Weaver Model of Communication (1948):
  • ​In 1948, Claude Shannon (mathematician & engineer) and Warren Weaver (scientist) introduced the Shannon-Weaver Model of Communication in the Bell System Technical Journal.
  • Originally designed to enhance technical communication, it later became a foundational model in communication studies.
• Key Components of the Model:
  • Sender (Information Source): Originates the message.
  • Encoder (Transmitter): Converts the message into signals (e.g., voice into sound waves or binary data for transmission).
  • Channel: The medium through which the message travels (e.g., cables, satellites).
  • Noise: External disturbances affecting transmission (e.g., network issues, environmental sounds).
  • Decoder: Converts signals back into a comprehensible message.
  • Receiver: The final destination of the message.
• Key Features:
  • Focuses on external noise that disrupts communication.
  • Highlights encoding & decoding processes in message transmission.
  • Originally developed for technical applications, later applied broadly in communication theory.
