Hello,
I'm not the best with computers but I'm doing an elective with uni and need to know what redndancy is and how it can be useful. Any help would be greatly appreciated
 
Redundancy is like having "run-flat" tires on a car. If one tire gets a flat you can still drive your car for another 50 miles or so; far enough to get home or to a repair shop.

Having a RAID array (except for RAID-0) provides redundancy.
If a drive fails you can continue functioning (with reduced performance) until you get the faulty drive replaced.
