Web5 mei 2024 · CPU gives access to the interrupt handler to process the interrupt. This entire process is called interrupt handling. Interrupt Handler is a process that runs when an interrupt is generated by hardware or software. The interrupt handler is also known as Interrupt Service Routine (ISR). ISR handles the request and sends it to the CPU. WebInterrupt handlers are initiated by hardware interrupts, software interrupt instructions, or software exceptions, and are used for implementing device drivers or transitions between protected modes of operation, such as system calls . The traditional form of interrupt handler is the hardware interrupt handler.
