# Failover | ![img \|150](https://upload.wikimedia.org/wikipedia/commons/thumb/9/9a/Duckfone.png/320px-Duckfone.png) | **Failover** is switching to a redundant or standby computer server, system, hardware component or network upon the failure or abnormal termination of the previously active application, server, system, hardware component, or network in a computer network. Failover and switchover are essentially the same operation, except that failover is automatic and usually operates without warning, while switchover requires human intervention. | | ------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | | wikipedia:: [Failover](https://en.wikipedia.org/wiki/Failover) |
