Q:
What are Interrupts?
A:
Interrupts are what your 4 year old generates every time you try to have any
kind of conversation with someone (just couldn't resist).
It's also a computer term (surprise). Normally called Interrupt Requests (IRQ),
they are basically calls made from a hardware device to get the "attention" of
the CPU (similar to the way a 4 year old gets an adult's attention, just not
as annoying).
For example, if a disk drive needs to get the attention of the CPU to perform
a task, it sends an "interrupt" that allows it to have access to the system.
