Interrupt cycle The interrupt cycle is a crucial part of a computer's operation that allows it to respond to external events or internal conditions that require immediate attention. It is a mechanism used to temporarily suspend the execution of the current program and transfer control to a specific routine known as an interrupt handler or interrupt service routine (ISR).Example Imagine a computer system with a keyboard connected to it. When you press a key on the keyboard, it generates an interrupt request (IRQ) to the CPU to notify it of the key press event. The interrupt cycle typically involves the following steps:Interrupt Request (IRQ): An interrupt request signal is generated by a device or a specific condition within the computer system.This signal informs the CPU that an event has occurred that requires its attention. ExampleYou press a key on the keyboard, which generates an interrupt request signal.
