Error correction is a process used to identify and fix mistakes in data or communication. In computer science, for example, it ensures that information sent over the internet arrives accurately. Techniques like checksums and parity bits help detect errors, allowing systems to correct them automatically, which is crucial for reliable data transmission. In everyday life, error correction can also apply to learning and education. When students make mistakes in their work, teachers provide feedback to help them understand and improve. This guidance helps learners recognize their errors and develop better skills, ultimately leading to greater success in their studies.
