    Developement of computer architecture is discussed in terms of the proliferation of the microprocessor, the utility of the medium-scale computer, and the sheer computational power of the large-scale machine. Changes in new applications brought about because of ever lowering costs, smaller sizes, and faster switching times are included

    What is the probability that the execution state of a given microprocessor running a given application is correct, in a certain working environment with a given soft-error rate? Trying to answer this question using fault injection can be very expensive and time consuming. This paper proposes the baseline for a new methodology, based on microprocessor error probability profiling, that aims at estimating fault injection results without the need of a typical fault injection setup. The proposed methodology is based on two main ideas: a one-time fault-injection analysis of the microprocessor architecture to characterize the probability of successful execution of each of its instructions in presence of a soft-error, and a static and very fast analysis of the control and data flow of the target software application to compute its probability of success. The presented work goes beyond the dependability evaluation problem; it also has the potential to become the backbone for new tools able to help engineers to choose the best hardware and software architecture to structurally maximize the probability of a correct execution of the target softwar

    Strange Bedfellows in the Personal Computer Industry: Technology Alliances between IBM and Apple

    Until recently technological development in the personal computer industry could be characterized by the competition between two basic designs. The current dominant design in this industry is associated with the IBM and Microsoft personal computing architecture. The other version of personal computing originated in the Macintosh computer from Apple Computer Company. In recent years we also see an increasing number of alliances between IBM and Apple. Joint technological development appears to be a major and somewhat surprising objective of these alliances. This paper analyzes the technology alliances between these companies in the context of recent technological changes, focusing on the timing and the objectives of these alliances. Technology partnering between these proponents of competing basic designs are found to only materialize several years after the DOS-based design of IBM and Microsoft had become dominant. This study is of a qualitative and exploratory nature, using both a small data set and two case studies.management and organization theory ;
