I prefer the terms:
data: raw input to a system of some sort
signal: values found in data that are of interest, that is, can become
information
noise: values found within the raw input data that must be removed
information: useful knowledge derived from some system.
Note that the "system" is highly context dependent: the input data for
one system could quite reasonably be the information output from
another. A concrete example:
data: samples of pressure received from a microphone transducer
signal: samples forming a recording of a sound wave
noise in the data: electromagnetic interference picked up by the
transducer
information: a waveform recording of the audio signal, minus mains
hum "noise".
data: a sampled waveform from an audio recording
signal: a recorded speech waveform
noise in the data: background wind noise recorded along with the
intended speech signal
information: phonemes corresponding to the spoken words.
