Connection to the world of hardware
- Internally, computers represent all information using the binary number system.
- Why? Electronic devices that are based on only two easily distinguishable states are
cheaper and more reliable than devices based on more than two states.
- It doesn't matter if the two states are 0 and 1, or "off" and "on", or "closed" and "open", or "low" and "high", or
- All that matters is that the two states be distinguishable and stable.

systems, see this handy
demonstration of number conversions.
