In a ____, a single communication path connects the network server, departmental servers, workstations, and peripheral devices.

In a Web-based system, portal design provides an important link between the user and the system, and poor design can weaken system effectiveness and value.

In all cases, a network must use a ____, which is a set of standards that govern network data transmission.

The ____ section in a typical system design specification describes the constraints, or conditions, affecting a system, including any requirements that involve operations, hardware, systems software, or security.

In addition to centralized data processing, early systems performed all data input and output at a central location, often called a(n) ____________________.

Company-wide systems that connect one or more LANs or WANs are called ____________________.

Various types of individual and site licenses are available from software vendors.

A client is a computer that supplies data, processing services, or other support to one or more computers. _________________________

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.
