Redundancy

Redundancy is the provision of functional capabilities that would be unnecessary in a fault-free environment. This can consist of backup components that automatically "kick in" if one component fails. For example, large cargo trucks can lose a tire without any major consequences. They have many tires, and no one tire is critical (with the exception of the front tires, which are used to steer, but generally carry less load, each and in total, than the other four to 16, so are less likely to fail).The idea of incorporating redundancy in order to improve the reliability of a system was pioneered by John von Neumann in the 1950s.
