Analog

From Styleguide

analog An internal representation system in a computer that uses a set of continuous values as opposed to discrete on/off values.

The distinction between analog and digital is not always useful in non-technical contexts. A digital system with enough values can mimic a meaningful range of analog values. For example, a high-resolution digital photograph or audio file may appear to have the same quality as an analog (film) photograph or recording.

In some cases, hardware manufacturers may use the term analog to indicate that a device features a wider range of control than usually expected from digital devices.
