Computers employ a variety of schemes to check whether a chunk of digital information–transmitted as a message, stored in a database, or functioning as a set of instructions–remains error-free. Such ...

Calculating an LDPC Note: the 3rd parity bit should be 0, not 1 LDPCs append a series of parity bits to a message. Usually the encoded stream is relatively long — 1024 bits would be a short message.

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 ...

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, ...

Error detecting and correcting codes are based on significant distance between two bit strings in terms of the number of bits that have to alter to get from the first ...
