Parity is calculated using XOR to bring the bytes to parity. That's where the name's from. The bits are XORed in series with each other with the output of the last step being an input to the next ...

The parity is computed by XOR'ing a bit from drive 1 with a bit from drive 2 and storing the result on drive 3 (to learn about XOR, see OR). After a failed drive is replaced, ...

The use of parity bits is a common method of detecting errors in data transmission and storage. Before looking at the use of parity bits in RAID, let's look more generally at their use as a method ...
