transverse parity check
A computing term for a parity check that operates across rows and columns, often in error detection for data transmission or storage.
Transverse parity check is one of the methods used for error detection in data.
A compound of 列 (column), 方行 (direction/row), 奇偶 (odd/even), and 検査 (check), literally 'column-direction odd-even check'. The exact historical derivation is uncertain; the term is a technical coinage in computing.
