Redundancy What is Redundancy in Networking? Redundancy in networking refers to the inclusion of backup systems or components to ensure continuity and reliability in case of a failure. Explanation Redundancy can involve duplicate servers, network paths, or power supplies, reducing the risk of downtime and improving fault tolerance. It is critical for mission-critical applications. Practical Example of Redundancy A data centre implements redundant power supplies and backup servers to maintain uninterrupted service during hardware failures.
