An operating system also has to be able to service peripheral ( ), such as timers,motors, sensors, communicationdevices, disks, etc. All of those can request the attention of the OS ( ) , i.e. at the time that they want to use the OS, theOS has to make sure it's ready to service the requests. Such a request for attention is called an interrupt. There are twokinds of interrupts: Hardware interrupts and Software interrupts. The result of an inteiTup: is also a triggering of theprocessor, so that it jumps to a ( ) address. Examples of cases where software interrupts appear are perhaps a divide by zero, a memory segmentation fault, etc. So this kind of interrupt is not caused by a hardware event but by a specificmachine language operation code. Many systems have more than one hardware interrupt line, and the hardwaremanufacturer typically assembles all these interrupt lines in an interrupt (请作答此空) . An Interrupt ( ) is a piece of hardware that shields the OS from the electronic details of the interrupt lines, so that interrupts can be queued and none of themgets lost.A.vectorB.arrayC.queueD.ist
