This section examined how human beings obtain data in the first place, by turning sensory data into something that can be communicated and reasoned about.
We ‘code’ this data using signs and symbols that are agreed within a community.
The section explored, again, the distinction between data and information, and noted that one person's data could be another's information.
It went on to describe how humans invented computers because we have a compelling interest in data, and the information we can derive from it. Modern computer systems with their incredible capabilities enable us to sense, store, process, transmit and display data in ways that were previously unimaginable.
