Signal to noise:
Data does not equal information. Data must be interpreted and understood in order to become information. Information does not equal knowledge. Knowledge is a construct that is created in the mind of the user as a result of accessing, processing and understanding information. Different individuals may extract different knowledge from the same information … or may extract no knowledge at all. No matter how sophisticated the medium; garbage in still produces garbage out. Noise cannot modify our expectations and to understand the sentence is not necessarily to understand the message. Are you missing the message?
