I got into an argument with a colleague about RAID levels (specifically RAID5) and whether the redundancy was accomplished through parity or ECC. The standard sources all refer to the RAID5 array ...

An error detection technique that tests the integrity of digital data in the computer. Parity checking adds an extra parity cell to each 8-bit byte of memory, thus ...

ECC adds multiple parity bits, though calculations are usually applied to complete words (typically 32 or 64 bits), not single bytes. Each ECC bit represents the parity of a different subset of the ...

I should add, I'm aware that there are (several) filesystems that do ECC/checksumming, but I'm really more interested in something that can store parity data in standard files. This seems to me to be ...

Correction is not possible with one parity bit since any bit error in any position creates exactly the same information as bad parity. If more bits are integrated ...

Not using a parity bit to check for errors. For example, an 8-N-1 setting in a communications program, which was widely used before the Web, means each character transmitted contains (8) eight bits, ...
