Windows has long used short audio cues to mark system events, including startup, alerts, and shutdown actions, although the exact sounds differ between releases.

Similar computer cues became common in online edits because their meaning is easy to recognize without explanation. They remain useful for tech nostalgia, abrupt endings, error jokes, and reaction videos in which a person appears to mentally switch off.
