Error detection and correction ensure data integrity from "summary" of Code by Charles Petzold
In the world of computers and digital communication, errors are an inevitable part of the process. Whether it's a stray cosmic ray flipping a bit or a momentary glitch in a transmission line, data can easily become corrupted as it travels from one place to another. This is where error detection and correction come into play. By implementing various techniques and algorithms, we can not only detect when errors occur but also correct them to ensure that the data remains accurate and intact. The concept of error detection involves adding extra bits to the data being transmitted so that any changes or errors can be easily spotted. These extra bits serve as a sort of checksum, allowing the receiving end to compare the original data with the received data and ide...
