TL;DR
A soffit vent is any intake ventilation opening in the eave underside, whether a continuous strip, individual rectangular louvers, or fully perforated panels, that supplies outside air to the attic. Cool air entering low and exhausting at ridge or gable vents carries off summer heat and winter moisture, protecting shingles and preventing the ice dams fed by a warm roof deck.
