error-detecting code; EDC
Technical computing term for a code that can detect errors in data transmission or storage, but not necessarily correct them.
We check data integrity using an error-detecting code.
Error-correcting code (ECC), which can both detect and correct errors, unlike エラー検出符号 which only detects them.
Compound of エラー (error), 検出 (detection), and 符号 (code). A direct calque from English 'error-detecting code'.
