WebThe way interrupts are handled varies between architectures. On x86, you store information about interrupts in an Interrupt Descriptor Table.

WebWhat is an interrupt? An interrupt is an event that alters the normal execution flow of a program and can be generated by hardware devices or even by the CPU itself. When an interrupt occurs the current flow of execution is suspended and interrupt handler runs.
