Higher the speed, higher the priority. Hard disk has the highest speed(MBps) among the given options and thus has the highest priority. Whereas, keyboard is the slowest one because we humans write so slow(like 1-3 word per second) when compared to CPU, and thus keyboard has lowest priority. You may have noticed sometimes that when you are copying/moving a large file on to your hard disk from other device, like pen drive, and then you try to type something using keyboard the typed words are shown with some lag. This is because of the priority being given to hard disk right now. 38 38 replyShare Please log in or register to add a comment.
Best answer 40 40 votes It should be a Hard disk. I don't think there is a rule like that. But hard disk makes sense compared to others here. http://www.ibm1130.net/functional/IOInterrupts.html Arjun answered Jan 22, 2015 • selected Jan 17, 2017 by naga praveen Arjun comment Share Follow See all 26 Comments 26 26 Comments reply Show 23 previous comments shashankrustagi commented Jan 19, 2021 reply Follow flag sir you roast students lol 1 1 replyShare GNANESWARA SAI commented Jan 27, 2023 reply Follow flag That time lapse is sufficient to handle the interrupt .

4 4 votes Devices with high speed transfer such as Hard disk (according to given options it has high speed among all) are given high priority, and slow devices such as keyboard receive low priority. So, clearly Hard disk is answer. Option (A).
