Encoding and decoding are fundamental processes in communication that enable the transmission and understanding of information. Encoding involves converting messages into a form that can be transmitted, while decoding involves interpreting the transmitted messages to extract their intended meaning. The sender, channel, message, and receiver are the key entities involved in this process. The sender originates the message, which is then encoded into a signal that can traverse the channel. The receiver decodes the signal, reconstructing the message based on shared knowledge and context. These processes work in tandem to facilitate effective communication.
