WebHardware interrupt is a kind of computer system interrupt that occur as a result of outside interference, whether that’s from the user, from peripherals, from other hardware devices or through a network. Hardware interrupt can be categorized into two types, they include Maskable interrupt and Non Maskable interrupts. WebAn 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. After the interrupt handler runs the previous execution flow is resumed. d2 wayfarer titleWebA hardware interrupt is an electronic signal from an external hardware device that indicates it needs attention from the OS.
