Abstract

Approaches to the attainment of reliable computer operation are considered in this paper. The goal is to assure correct execution of programs using less than perfect components. The discussion includes design methodology, fault classification, redundancy techniques, reliability modeling and prediction, and examples of fault-tolerant computers. The last section identifies some relationships between reliability methods for hardware and for software.
