What is an exception condition in a computer system caused by an event external to the CPU known as ?

  • A.Halt
  • B.Process
  • C.Interrupt
  • D.
    None of above

Answer: C

Correct answer: Interrupt

An interrupt is a signal raised by something outside the CPU - a device, a timer, an error condition - that causes the processor to break off what it is doing and attend to it. A halt stops the processor rather than diverting it, and a process is a program in execution.
