There are basically 3 kinds of redundancy that are implemented in most systems: hardware, software, and environmental. Systems designed with high availability in mind protect against interruptions and prevent outages from happening in the first place. Your wired system, or Local Area Network (WLAN), includes a storage technology called Redundant Array of Independent Disks (RAID) that writes data across multiple discs. Redundancy is good!
