Examines major network structures and provides criteria for selecting the best layout. Describes daisy-chain, star, bus, tree, ring, and token ring topologies. Discusses factors to consider when connecting computers, including user needs, printing demands, modem and file sharing, user grouping, the physical plant, and connective equipment. (AEF)

Discussion of information system design proposes the artifact as theory perspective and suggests that information system design is best tackled by user-centered theories and methods. Topics include the software development process, human-computer interaction, and implications for information science. (LRW)

Describes how an understanding of "engagement" can be applied to multimedia systems design and can support learning goals and motivation. Provides examples of engaging interactions, suggests methodologies for evaluating their impact on the learner, and offers practical hints for incorporating them into multimedia system design.…

Presents a formal object-oriented specification model (OSS) for computer software system development that is supported by a tool that automatically generates a prototype from an object-oriented analysis model (OSA) instance, lets the user examine the prototype, and permits the user to refine the OSA model instance to generate a requirements…
