The beans sit in the hopper and are ground on demand. This is the faster way in everyday life, especially if the same coffee is used all the time. A full hopper, however, means that the beans at the bottom are exposed to the air for longer.
The diameter of the grinding burrs determines how many revolutions are needed for the same amount of coffee. Larger burrs need fewer revolutions, the grind warms up less, and heat in the grind reduces aroma.
Flat burrs grind with two parallel rings and deliver a tight particle size distribution. You do not recognize dull burrs by appearance but by the fact that the shot runs faster than usual.
With the grind size you control how quickly water passes through the coffee grounds. It is the first adjustment you make when an espresso is too acidic or too bitter.
The grinder weighs itself and grinds until the set amount is in the portafilter. That stays the same even when the bean changes or the bag gets emptier, where a time-based control would need readjusting.
The grinder output indicates how much ground coffee comes out per second. For a single drink you hardly notice it, as extraction and milk determine the time. You only feel it when many drinks are made back to back.
The manufacturer's guideline for how much coffee the burrs can handle before they should be replaced. You do not notice dull burrs by their appearance but because the extraction runs faster than usual at the same setting.
