An application crash occurs when a software program unexpectedly stops working, often resulting in the loss of unsaved data. This can happen due to various reasons, such as coding errors, memory overload, or compatibility issues with the operating system. When an application crashes, it may display an error message or simply close without warning. Users may experience frustration during an application crash, as it interrupts their tasks. To prevent crashes, developers often conduct testing and debugging, while users can ensure their software is updated and compatible with their devices. Common examples of applications that may crash include web browsers, games, and productivity tools.
