31. :These two papers introduced and studied the problem that is nowadays known as Byzantine fault tolerance . 32. This level is recommended for applications that require high fault tolerance , capacity and random access performance. 33. Fault tolerance is notably successful in computer applications.34. See the section on fault tolerance below. 35. Fault tolerance is the ability of a system to continue operation in the presence of a fault.36. The save mechanism provides fault tolerance . 37. It is obvious that fault tolerance must be a key consideration in the early stage of software development. 38. Clustering increases availability and fault tolerance of server installations by distributing and replicating the service among many servers. 39. Systems often incorporate redundancy or fault tolerance so that they do not fail when an individual component fails. 40. A switch with a faster backplane can be just as good for performance, if not for fault tolerance .
