exceptions

n. something that is out of the ordinary, anomaly; objection, opposition

Exception handling is a programming language construct or computer hardware mechanism designed to handle the occurrence of some condition that changes the normal flow of execution. The condition is called an exception. Exceptions are normally recommended to be used only for signaling error (exceptional) conditions. For signaling conditions that are part of the normal flow of execution see the concepts of signal and event handler.

n. exception

guru meditation 

An error condition that changes the normal flow of control in a program. An exception may be generated ("raised") by hardware or software. Hardware exceptions include reset, interrupt or a signal from a memory management unit. Exceptions may be generated by the arithmetic logic unit or floating-point unit for numerical errors such as divide by zero, overflow or underflow or instruction decoding errors such as privileged, reserved, trap or undefined instructions. Software exceptions are even more varied and the term could be applied to any kind of error checking which alters the normal behaviour of the program.
