In telecommunication, a longitudinal redundancy check (LRC) or horizontal redundancy check is a form of redundancy check based on the formation of a block check following preset rules: Copy of the original phone of Alexander Graham Bell at the Musée des Arts et Métiers in Paris Telecommunication is the assisted transmission of signals over a distance for the purpose of communication. ... In telecommunication, a redundancy check is extra data added to a message for the purposes of error detection and error correction. ...

• The block check formation rules are applied in the same manner to each character.
• A combination of longitudinal and vertical redundancy check allows the detection and correction of single bit errors.

A longitudinal redundancy check character, which is used to verify that data has been received without error, may be computed from any sequence of characters by the following algorithm: In telecommunication, a transverse redundancy check (TRC) or vertical redundancy check is a redundancy check for synchronized parallel bit streams, (a) that is based on the formation of a block check following preset rules, (b) in which the check-formation rule applied to blocks is also applied to characters, and... In computer science and information theory, error correction consists of using methods to detect and/or correct errors in the transmission or storage of data by the use of some amount of redundant data and (in the case of transmission) the selective retransmission of incorrect segments of the data. ...

 Set LRC = 0 While there is another character in the string do Set c equal to the next character Set LRC equal to LRC XOR c end do 

LRC XOR c specifies that corresponding bits of LRC and c should be exclusive-or’ed and the resultant bit values should become the values of the corresponding bit of the result. Exclusive disjunction, also known as exclusive or and symbolized by XOR or EOR, is a logical operation on two operands that results in a logical value of true if and only if one of the operands, but not both, has a value of true. ...
