The device connect chime is part of the Windows operating system sound scheme, assigned to the event that fires when new hardware is detected. Versions of the sound have shipped with Windows for years, so most computer users learn it passively while setting up printers, phones and storage devices. On soundboards and in meme edits that everyday familiarity became the joke, with creators replaying the chime out of context to suggest anything from a brain loading to a person being plugged in.
