Active dry yeast vs Instant yeast
Both are dried yeast. Instant is milled finer and dissolves fast, so you can stir it straight into the flour; active dry is traditionally proofed in warm water first, though many modern brands no longer require it. They swap about 1:1 by weight — a standard packet is 7 grams, or 2¼ teaspoons, of either. Instant is a little more potent, so some bakers trim it slightly, and bread-machine recipes often cut it by about a quarter. Either gets you there; instant just shaves time off the first rise.
