    Analogies with biological disease with topological considerations added, which show that the spread of computer viruses can be contained, and the resulting epidemiological model are examined. The findings of computer virus epidemiology show that computer viruses are far less rife than many have claimed, that many fail to thrive, that even successful viruses spread at nowhere near the exponential r...

    The advantages of semiconductor lasers that produce shorter wavelengths and the underlying physics that make them difficult to achieve are examined. The breakthroughs that have brought a semiconductor laser within reach are described. These include advances in fabricating and doping the large bandgap II-VI semiconducting compounds ZnSe and ZnS on which the new lasers are based and the development ... View full abstract»

    Factors to consider when choosing between workstations and supercomputers are identified. Applications and computers are categorized, and speed requirements as a driving force in computer development are examined. It is shown how to analyze an application to determine the type of system that can best solve the problem, and the types of problem for which workstations are best are discussed.<<...

    The results of an in-depth survey conducted to determine the role IBM-compatible and Macintosh computers play in the daily lives of IEEE Spectrum readers is presented. About 45% of the respondents were in management; 9% were in general or corporate management, and the majority were engineering managers or project leaders/engineers. About 20% of the respondents were involved with R&D or design ... View full abstract»
