Most companies resolved the problems of stand-alone computing by joining clients into a(n) ____________________ that allows sharing of data and hardware resources.

-In a three-tier design, as illustrated in the accompanying figure, the middle layer can be thought of as a(n) ____________________, because it provides the application logic, or business logic, required by the system.

During the final design stage, you make decisions that will have a major impact on the initial costs and TCO for the new system. At this point, you should review all previous cost estimates and ask a series of questions. List at least six of the questions you should ask at this point.

____ technology relies on multiple data paths, also called multipath design, to increase bandwidth and range.
