| Abstract: Real computer-based systems fail, and hence are often far less dependable than their owners and users need and desire. Individuals, organisations and indeed the world at large are becoming more dependent on such systems, so there has been much work on trying to gain increased understanding of the many and varied types of faults that need to be prevented or tolerated in order to reduce the probability and severity of system failures. In this paper I analyze the concept of system faults and failures, and discuss the assumptions that are often made by computing system designers regarding faults, and a number of continuing research issues related to fault tolerance. | |||||||||||||||||
