ln this paper, the basic definitions and the associated terminology used in fault tolerance domain are presented, in an objective but dida tic way, emphasizing the dependability concept in computer systems, its impairments, the means to reach it and its usual measures. ln the se quence, there are discussed fault confinement, detection, diagnostic and treatment, including techniques and mechanisms of error processing as recovery and reconfigura tion.
Este artigo apresenta, de forma objetiva mas didática, conceitos bási cos e a terminologia da área de Tolerância a Falhas, enfatizando o con ceito de segurança em sistemas de computaçâo, os fatores que comprome tem esta segurança, os meios para alcançá-Ia e as suas medidas usuais. Na seqüência, sâo discutidas as técnicas de confinamento, detecçâo, di agnóstico e tratamento, incluindo técnicas e mecanismos de recuperaçâo e reconfiguraçâo.
