Error correction is a process used to identify and fix mistakes in data or communication. It is essential in various fields, including computer science, telecommunications, and linguistics. For example, in computer networks, error correction techniques ensure that data sent over the internet arrives accurately, even if some bits are lost or altered during transmission. In language learning, error correction helps students improve their skills by addressing grammatical, pronunciation, or vocabulary mistakes. Teachers often provide feedback on written or spoken work, guiding learners to recognize and correct their errors. This process enhances understanding and promotes better communication in the target language, such as English or Spanish.
