>digital virtual: binary-encoded data

Arguably the raw binary data still has a physical aspect, because it hasn't been interpreted yet (other than a reordering by the file system). The virtual thing is what the data ultimately represents.

Another subtlety is that a drawing on a page would be an analog representation of the thing, but if the drawing has the shape 右 and the page is placed between two doors, there would be a virtual idea encoded digitally as well.
