The RAM in our computers is constantly refreshed to ensure that it maintains the intended information. For most of us, however, a bit flipped somewhere in the memory of our cell phones or laptops is ...

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.

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 ...

An error condition that occurs when the parity bit of a character is found to be incorrect. See parity checking. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other ...

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 ...

Several techniques can be used to efficiently implement a Hamming coder for single-bit error correction and double-bit error detection. Many error-correcting codes ...

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 ...

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 ...
