    I'm currently doing my Network+ and have just finished the RAID unit. Could someone please explain exactly what parity is and what it does. I know that its an error detection technique but after that I go west.

    Thanks

    Hi fear-and-loathing, and welcome :D

    Again, what Trip and Sandy said. All I'd add is that, for the purposes of Network+ (and prob a great deal more), you will not need a deep understanding of parity.

    Effectively, it is the result of an algorithm run across the data on the drives, that is unique to that data, therefore by reversing the algorithm, the data can be re-created.

    I haven't checked out the link above, so if what I've said is cr@p, then sorry - I am just an armadillo you know :eek:

    Take it easy, mate :D
