ISO 1155:1978 Overview

ISO 1155:1978 is an international standard developed by the International Organization for Standardization (ISO) that defines the use of longitudinal parity for detecting errors in information messages during data communication and processing. This standard addresses the need for reliable error detection in systems transmitting data using the 7-bit coded character set (ISO 646) and provides a robust method to identify errors by attaching a block check character to information blocks or text.
