Explain why it is important that the device registration is the last thing that is done in the initialization routine of a device driver. Likewise, explain why un-registering a device must happen first in the exit routine of a device driver.

Answers

Answer 1

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.

What is role of a device driver?

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.

* DOESN'T HAVE TO BE RELATED TO ANY SUBJECT IN PARTICULAR I JUST SELECTED COMPUTER AND TECH CAUSE THATS THE CLASS I'M DOING THIS FOR.

Answers

Answer:

Explanation:

1. All Computer Science and tech courses rock. However, they won’t cover all the skills you might need in a job. For example, if you’re planning to go into software development, you might learn a considerable amount of programming languages, but you may need to go beyond that for work.

You may have to understand and get the hang of new programming languages on your own, without anyone to teach you. It might be a good idea to look for introductions.

So schedule your time properly and after completing your core assignments, hit G.o.o.g.l.e, and find out what type of computing skills are tech companies looking for. Particularly, look into further details on the exact requirements at those specific companies you dream of working for.

You could also make little websites or programs just for yourself, to test your abilities and push yourself further.

If want to study Information Technology at top-ranked universities, check programmes offered by some of the best universities ranked by The Times Higher Education.

2. Try to get your assignments done well in advance of deadlines, ideally have them ready a week in advance. Otherwise, you’ll just get tired, your code won’t work, and you’ll fail the assignment.

Computer Science and tech is one of those areas where it is absolutely necessary to keep working throughout the semester because sometimes you’ll need to take a break to get some clarity as to why something isn’t working. So do yourself a favour and work all the way through the semester.

That doesn’t mean you should spend every minute studying; it means you’ll have to be constant with your learning progress throughout the year. You’ll do far better this way.

3. What do you learn during Computer Science degrees? Most tech courses are not all theory compared to courses from other types of degrees. Even if Computer Science and Information Technology degrees include theoretical classes, their approach is far more practical.

For instance, right after a theoretical class, you will have to apply that knowledge through practical exercises in a computer laboratory.

Sure, you may have to work on essays, but they will always have to include practical work or projects – both successfully combined, with logical explanations for each step and chapter from your work.

4. Being able to work on your own and independently motivate yourself is great, and you’ll need that. But don’t forget that you’re not alone, and its’ highly unlikely you’ll be alone in the workplace as well. You’re likely to be part of a team.

And team work takes some skills you’ll need to brush up on and work constantly. Once you’ll find a good study group, you’ll surely enjoy to meet with your peers, share ideas and work on interesting projects. After all, that’s just the classical way innovation starts: with a few genius minds that come together and work on a new invention until it becomes trademark.

5. If you study a Computer Science degree, it may seem pretty daunting as you'll need to learn more, study more, do more. But don’t forget to live your life. Have fun, meet up with friends, go clubbing or travelling, get involved in some student activities.
