A "Quad" typically refers to a quadrangle, which is an open space or courtyard surrounded by buildings, often found in educational institutions like universities. These areas serve as social hubs where students can gather, study, or relax. Quads often feature grass, benches, and pathways, creating a pleasant environment for outdoor activities. In addition to its architectural meaning, "Quad" can also refer to a four-wheeled vehicle, such as an all-terrain vehicle (ATV). These vehicles are designed for off-road use and are popular for recreational activities, including trail riding and racing. They provide a fun way to explore rugged terrains.
