 The fragment is stored at an address pointed to by an interrupt 
      vector. Interrupts can be triggered by hardware. For example a key press 
      or the printer running out of paper cause a hardware interrupt. The CPU 
      switches to the code that handles the interrupt. When finished, the CPU 
      continues with its earlier task.</td>
