LRC (Longitudinal Redundancy Check)

A longitudinal redundancy check is an error-detection process that determines the validity of transmitted data. It occurs automatically during data transmission and is meant to guard against errors that may occur during the transmission process. These errors are not caused by any user action. Instead, they occur as a result of a glitch that may arise. If the check finds an error, the two streams are simultaneously examined to determine where the error has occurred. The error is then located and corrected.

What Small and Midsize Businesses Need to Know About LRC (Longitudinal Redundancy Check)

The use of longitudinal redundancy checks occurs in many instances. The sender of data may not even be aware that such checks have occurred. LRCs will ensure the accuracy of data that a small business transmits from one source to another. Fortunately, since they happen automatically, there is no direct impact or anything a small business needs to do to ensure that their data has an LRC run on it.
