👉 Crashing is a technical term in computer science that refers to an error or failure of a software system, hardware device, or application that results in the operation of the system failing. It can be caused by various issues such as hardware failures, software bugs, or unexpected input from the user or system. In a crash, the program attempts to execute a function or method that is not defined or does not work correctly. This leads to an error message being displayed on the screen and the program crashing.
