Explain why it is important that the device registration is the last thing that is done in the initialization routine of a devic

The reason why device registration is the last thing done is that if any errors happens at the time you register device, you have to undo the registration activities and as such, it is often done last.

<h3>What is role of a device driver?</h3>

The device driver is known to be the device that gives the other part  of the operating system the needed software interface or the device class.

The reason why un-registering a device must happen first in the exit routine of a device driver is because if there is an issue, one has to settle it first before registration as one does not want error.

Conclusively, If any kind of errors is seen when a person wants to register the device, the person must undo any kind of registration that has been performed before that error occurs.

Which of the following shows a list of Big-Oh running times in order from slowest to fastest?
Rufina [12.5K]

Answer:

O(N!), O(2N), O(N2), O(N), O(logN)

Explanation:

N! grows faster than any exponential functions, leave alone polynomials and logarithm. so O( N! ) would be slowest.

2^N would be bigger than N². Any exponential functions are slower than polynomial. So O( 2^N ) is next slowest.

Rest of them should be easier.

N² is slower than N and N is slower than logN as you can check in a graphing calculator.

NOTE: It is just nitpick but big-Oh is not necessary about speed / running time ( many programmers treat it like that anyway ) but rather how the time taken for an algorithm increase as the size of the input increases. Subtle difference.

Assume that cell F5 to F10 In a spreadsheet contains numeric value of salary earned by some workers and cell F12 contains the va
snow_tiger [21]

Answer:

=F5*$F$12+F5

Explanation:

If we want to increment the salaries in the cell F5, we must multiply the cell F5 by cell F12, and then we must sum that result.

If we want to drag the formula from the cell F5 to F10, we must use the dollar symbol $ to apply the same percent in our formula.

For example:

F12 = 5% = 0.05

F5 = 10,000

=F5*$F$12+F5

=10,000×0.05+10,000 = 10,500
