What does a interrupt controller do?

Data is transferred across the internal "bus" (just a term for the common communication medium inside the computer). When a device (disk drive, video card, peripheral controller) wants to send data it raises it's interrupt "flag", to let the interrupt controller know that it has a request. Based on priorities and timing, the interrupt controller "grants" access to the bus and the device is allowed to send data. Imagine a signal light at a complex intersection. A data collision on the bus would result in immediate failure and the computer would crash.
