Or when transmitting data packets over a network you want to favor real time data like phone or video calls over file downloads. And in case of a failed transmission you want to just forget about the few milliseconds of voice you just lost but you certainly want to retransmit a lost packet from the middle of a binary. It's all the same, identifying objects with different characteristics in order to handle them with tailored algorithms instead of simply using a generic but less optimal algorithm for all objects.
