Some of the key problems with information systems that show up later in the systems development life cycle can be traced back to inadequate work during requirements determination. How might this issue be avoided?

You would have to go back to school in order to earn your diploma in information systems. The choice of taking either online courses or attending a college is up to you.

The normal power back up would be a battery. Some may come with a back up battery pack already built it. Other's you may need to buy one for and have it professionally installed.

It is okay that you forgot the answer to your security question. Many times these systems have back up plans in this event.
