Reliability and Availability Techniques for Computer Fault Tolerance

Abstract

Users are not concerned with the computer faults, but they need thecomputer working in a correct mode specially in criticalcircumstances. Fault Tolerant Computing (FTC) plays a important roleespecially since early fifties. This area opens a wide aspect to beresearched are4 it involves varieties of categorizations of techniquestowards the effort to make system fault tolerant, modeling and testinghelping with system development, and bench-marking to evaluate andcompare systems. The concept, model, and methodology of faulttolerant computing are very much controversial to software while theyare considered fairly mature for hardware. Often refer to real-timecritical systems as embedded systems. Fault tolerant computing farfrom strictly application the system development and operationalprocess in the above area.
