A "crash" typically refers to a sudden and unexpected event where something fails or breaks down. In the context of computers, a crash occurs when a program or the entire system stops working, often leading to the loss of unsaved data. This can happen due to various reasons, such as software bugs, hardware failures, or conflicts between different applications. In the world of vehicles, a crash describes an accident where cars or other vehicles collide. This can result in damage to the vehicles and, unfortunately, injuries to the people involved. Road safety measures, like wearing seatbelts and following traffic rules, are essential to prevent such crashes and keep everyone safe on the road.
