Fault-Tolerant Systems

Fault-Tolerant Systems

General Description

Computers and networks are increasingly used in critical applications, where system failures can be expensive or even catastrophic. Example applications include aircraft fly-by-wire control, automobile control, computers used in medical systems, spacecraft, and databases in a large variety of financial and enterprise applications. The overall reliability expected of a computer system in these applications far exceeds that of any individual computer. This course is about how to build a highly reliable system that continue to function acceptably even after a number of its components (hardware or software) have failed
