Fault tolerance and redundancy are related concepts that work together to ensure reliable and uninterrupted operation of a system.
Fault tolerance refers to a system's ability to continue functioning even in the event of a failure or fault. This can be achieved through the use of various techniques such as error detection, error correction, and redundancy.
Redundancy, on the other hand, refers to the presence of extra components or resources in a system that can take over the functions of failed or faulty components. Redundancy is often used as a means of achieving fault tolerance.
In other words, redundancy is one of the approaches used to achieve fault tolerance. A redundant component or resource can take over the function of a failed component, allowing the system to continue functioning without interruption. Therefore, the relationship between fault tolerance and redundancy is that redundancy is used to achieve fault tolerance.
