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. 30 votes 30 votes Please log in or register to add a comment.
Best answer 37 votes 37 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 25 Comments See all 25 25 Comments reply Show 22 previous comments marvellouschandan commented Oct 25, 2020 reply Follow Share What if I press “ctrl +c” command to terminate some process or might be I gave “sudo rm -rf /” and suddenly press ctrl + c, I believe keyboard should be given more priority.

3 votes 3 votes Hard disk should be given higher priority as all user programs and OS are stored in here.

It's a rule. From highest to lowest. THERMAL MONITOR -> LOCK -> KEYBOARD -> SERIAL PORT -> HDD -> FLOPPY DISK -> PRINTER 1 votes 1 votes adm1n123 commented Nov 20, 2018 reply Follow Share @krishna Please provide references me too think it should be keyboard. 0 votes 0 votes Gaurav Yadav commented Apr 22, 2020 reply Follow Share Highest priority is given to the device which has high probability of data loss. 0 votes 0 votes Please log in or register to add a comment.
2 votes 2 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).
