Forward error correction (FEC) is a method used in data transmission that allows the receiver to detect and correct errors without needing a retransmission of the original data. This is achieved by sending extra redundant data alongside the original information, enabling the receiver to identify and fix errors that may occur during the communication process. FEC is particularly important in scenarios where low latency is crucial, as it helps manage communication protocols by minimizing the need for back-and-forth exchanges.
congrats on reading the definition of forward error correction. now let's actually learn it.
