What are
External Storage: Files could be stored on an external flash disk or hard drive. Files could also be stored on a mobile phone or any storage device that is peripheral to the main operating system. Failover System: switching to a redundant or standby computer server, system, hardware component or network upon the failure of the system. Redundancy: these are computers that have duplicated data, however unlike a failover system, this system does not take over the initial system’s requests.
