Hardware interrupt vs software interrupt
WebNon-maskable interrupt. In computing, a non-maskable interrupt ( NMI) is a hardware interrupt that standard interrupt-masking techniques in the system cannot ignore. It typically occurs to signal attention for non-recoverable hardware errors. Some NMIs may be masked, but only by using proprietary methods specific to the particular NMI.
