Fault-Tolerant Computing: An Introduction

THE first Special Issue on Fault-Tolerant Computing was published in this TRANSACTIONS nearly a decade ago [1]. Five other Special Issues devoted to this same topic followed [2]-[6]; this is the seventh in the series. These seven issues contain a representative sample (over 120 papers and correspondences) of the research activities that have taken place in fault-tolerant computing over the past decade. It is therefore tempting, in perusing these issues, to look for possible trends in this activity.
