4.14 A final word

I've looked at specific techniques for taking features of our analogue world across the boundary into the digital realm. All these methods have worked along the same lines – a two-step process consisting of:

  1. breaking the target into parts; and

  2. mapping each part onto a binary number.

But I want to remind you of two points. First, we are not restricted to visual or sound information. Using the same strategy, we can take any feature of our world that interests us into the digital world. Second, once this information has been captured in digital form, there is no reason why it need just be stored and exchanged – we have other options. We can manipulate it in any way we want, an idea I discuss.. Before I move to this, however, I want to delve a bit deeper into what digital information means.
