What an update really touches
It helps to remember that an update at this layer changes the software, never the hardware. The physical component stays exactly as it was; what changes is the translator guiding it. An update might smooth a rough edge, teach the translator a better way to work, or close a gap that was discovered after release.
Knowing this takes much of the mystery out of updates. They are not rebuilding your machine; they are refining the instructions that drive a part you already own, usually in small and specific ways.
