Final answer:
The roles of sender, encoding, and other elements are part of the communication process, which varies with different mediums. The encoding of a message changes with the medium, which can alter interpretation and impact, and decoding messages from different cultures or species can be challenging but is crucial for successful communication.
Step-by-step explanation:
The roles of sender, encoding, the message, selecting a medium, decoding, creating meaning, feedback, noise are all elements that play a role in the communication process. These components are essential in understanding how information is conveyed between individuals and groups. In the context of different mediums, this dynamic can significantly vary.
When a message is encoded in a signal, like in a video, the message is constructed using a combination of modes such as images, audio, and text. The medium used to deliver the message, whether through video, radio, or print, can alter the interpretation and impact of the message. Marshall McLuhan's famous statement 'the medium is the message' highlights the concept that the medium itself influences how the message is perceived and understood.
The encoding and decoding of messages are vital in cross-cultural or cross-species communication scenarios, such as potentially decoding a message from an alien species. The success of such communication would depend on recognizing patterns or systems within the signal that may represent a form of language or data. In this respect, the encoding of a message is not invariant, as the medium and the cultural or contextual understanding of the recipient play significant roles in the communication process.
