Error Correction Code

Error Correction Code (ECC) is a method used in digital systems to detect and fix errors that may occur during data transmission or storage. When data is sent or saved, ECC adds extra bits—redundant information—that help identify and correct mistakes without needing to resend the data. Think of it like a spell check for digital information, ensuring accuracy even if some bits get corrupted. This enhances reliability in devices like computers, smartphones, and data servers, maintaining data integrity and reducing errors during communication or long-term storage.
