`
`interpreter A translator for a high-level programming language ’
`that translates and runs the program at the same time.‘lnter—
`preters are excellent for learning how to program because, ifianp,
`error occurs, the interpreter shows you the likely place (and
`sometimes even the cause) of the error.You can correct the
`problem immediately and execute the program again, learning
`interactively how toicreate a successful program.'How'ever,'
`interpreted programs run much more slowly than compiled
`programs. See compiler

`interrupt A signal to the microprocessor indicating that an event

`
`interrupt controller Part of the motherboards chip set that
`distributes hardware interrupt request (IRQ) lines. The interrupt
`controller prevents '=more than one peripheral device from com-
`municating with the microprocessor at one time.
`
`interrupt handler A program that executes when an interrupt
`i
`occurs. -Such programs deal with events that are far below the ~
`threshold of user-perception; for example, they deal with matters .
`as minute as the reception of characters from the keyboard
`input.
