Error Correction Codes
Error Correction Codes (ECC) are mathematical algorithms used to detect and correct errors in data transmission or storage, ensuring data integrity in noisy or unreliable communication channels. They work by adding redundant information (parity bits) to the original data, enabling the receiver to identify and fix errors without retransmission. Common applications include digital communications, memory systems, and data storage technologies.
Developers should learn ECC when working on systems requiring high reliability, such as telecommunications, satellite communications, or data storage solutions where errors are inevitable. It is essential for implementing robust error handling in protocols like Wi-Fi, cellular networks, and RAID storage arrays, ensuring data accuracy and system resilience in real-world conditions.
