An interrupt driven device driver is one where the hardware device being controlled will cause a hardware interrupt to occur whenever it needs to be serviced. For example, an ethernet device driver would interrupt whenever it receives an ethernet ...

WebThe main difference between polling and interrupt is that the CPU checks I/O devices at regular intervals in polling to see whether they require CPU service. On the other hand, in the interrupt method, the input/output device interrupts the processor and alerts it that it requires processor service. In this article, you will learn about the ... Webdriver, which translates the requests into device I/O com-mands specific to the backing storage device. Upon finishing an I/O command, a storage device is ex-pected to raise a hardware interrupt to inform the device driver of the completion of a previously submitted com-mand. The device driver’s interrupt service routine then

WebIn computer science, polling or a polled operation denotes the process of repeatedly sampling the status of external devices by a client program. The term polling is often used when describing input/output and referred to as software-driven I/O or polled I/O.
