Fault tolerance refers to the ability of a system, particularly in computing and engineering, to continue operating properly in the event of the failure of some of its components. It involves designing systems in such a way that they can tolerate errors or failures without complete disruption of services or loss of data. Key aspects of fault tolerance include: 1. **Redundancy**: This involves duplicating critical components or functions of a system to provide backup options in case of failure. This can include hardware redundancy (e.
