Answer:
Highest
Explanation:
A interrupt request / IRQ is in which instructions are sent to Cpu and uses an interrupt handler to run distinct program . Hardware interrupts are used to manage occurrences such as obtaining modem or network card information, important presses, or mouse motions.
- Interrupt request 0. – it is a system timer (can not be altered)
- Interrupt request 1 – keyboard controller (can not be changed)
- Interrupt request 2 – cascaded IRQ 8–15 signals (any device configured to use IRQ 2 will genuinely use IRQ 9)
- Interrupt request 3 – serial port 2 controller
- Interrupt request 4 – serial port 1 controller
- Interrupt request 5 –parallel port 2 and 3
- Interrupt request 6 - floppy disk controller
- Interrupt request 7 –parallel port 1. If a printer is not present, it is used for printers or for any parallel port. It can also possibly be shared with a secondary sound card with cautious port management.
As interrupt number increases priority level decreases, Priority level 0 is the highest priority level .

Answer:
Device management controls peripheral devices by sending them commands in their proprietary machine language. The software routine that deals with each device is called a "driver," and the OS requires drivers for each of the peripherals attached to the computer.
Explanation:
Answer:
Interest
So, lets say that you took a loan from the bank of 20,000. But, when you are supposed to pay it back, you need to pay 25,000. This is because of interest. When the bank gives you the money, they cannot give it to you just like that. There is no profit coming from it. So, there is the thing called interest which basically says that since you took money from the bank, you need to pay a little more because you borrowed money from them.
