Describe a technical system (networks and applications are two examples, but there are many others) you are familiar with and all of its technical components (there should be at least six, but no more than ten). Explain in lay terms the approximate incremental costs involved in equipment and people to make a system increasingly more available. Use the Internet, Walden Library research, or your personal experience to estimate the costs. Choose at least three availability targets for your comparison. Examples of availability targets are standard business hours, 99.9% availability (acceptable down time for a single failure of approximately eight hours each year) and 99.999% availability (virtually no downtime).
