keskeytyksistä
Keskeytyksistä, also known as interrupts in English, are signals sent to the processor by hardware or software that temporarily halt its current execution. These signals indicate that an event has occurred which requires immediate attention. When an interrupt is received, the processor suspends its ongoing task, saves its current state, and then executes a specific piece of code called an interrupt handler. This handler is designed to deal with the event that triggered the interrupt. Once the handler has finished its work, the processor restores its saved state and resumes the interrupted task.
Interrupts are a fundamental mechanism in modern computing, enabling efficient multitasking and responsiveness. They are broadly
The interrupt mechanism allows the processor to handle multiple tasks and events concurrently without constantly polling
