| Question 24 |
A computer handles several interrupt sources of which the following are relevant for this question.
- . Interrupt from CPU temperature sensor (raises interrupt if
CPU temperature is too high)
. Interrupt from Mouse(raises interrupt if the mouse is moved
or a button is pressed)
. Interrupt from Keyboard(raises interrupt when a key is
pressed or released)
. Interrupt from Hard Disk(raises interrupt when a disk
read is completed)
Which one of these will be handled at the HIGHEST priority?
| Interrupt from Hard Dist | |
| Interrupt from Mouse | |
| Interrupt from Keyboard | |
| Interrupt from CPU temperature sensor |
Question 24 Explanation:
The interrupts of higher priority are assigned to requests which, if delayed, can cause serious problems. High speed transfer device such as magnetic disks are given higher priority, and slow devices such as keyboard, mouse receive low priority. Also delaying a CPU temperature sensor can cause serious problems like can damage CPU.
Therefore, we can say that priorities are,
CPU temperature sensor > Hard disk > Mouse > Keyboard.
Therefore, we can say that priorities are,
CPU temperature sensor > Hard disk > Mouse > Keyboard.
Correct Answer: D
