Translation guide
A code that can detect errors in data, often used in computing and telecommunications. In Japanese, this is typically expressed with compound terms using 誤り検出 (error detection) or エラー検出 (error detection).
The learner wants to refer to any code designed to detect errors in data transmission or storage.
Standard technical term. 誤り (error) + 検出 (detection) + 符号 (code). Used in information theory and communications.
この誤り検出符号は、データの整合性を保証します。
This error-detecting code ensures data integrity.
Loanword version using エラー (error) and コード (code). Common in IT contexts.
The learner wants to refer to a particular kind of error-detecting code, such as parity check or CRC.
Parity check code. Often simply called パリティチェック.
パリティチェック符号は単一ビット誤りを検出できます。
Parity check codes can detect single-bit errors.
Both 誤り (ayamari) and エラー (erā) mean 'error'. 誤り is more formal and traditional, while エラー is common in IT and casual contexts. In technical documents, 誤り検出 is standard, but エラー検出 is also widely understood.
Error-detecting codes only identify errors; error-correcting codes (誤り訂正符号) can fix them. Be careful not to confuse the two. If you need to emphasize detection only, use 検出 (kenshutsu).
エラー検出コードを実装する必要があります。
We need to implement an error-detecting code.
More explicit: 'code for error detection'. Less common but still valid.
誤り検出用符号の設計は複雑です。
Designing an error-detecting code is complex.
Cyclic Redundancy Check code. Widely used in networks and storage.
CRC符号はバースト誤りに強いです。
CRC codes are robust against burst errors.
Checksum, a simple error-detecting method. Often used without 符号.
チェックサムを使ってデータの誤りを検出します。
We detect data errors using a checksum.
Hamming code, an error-correcting code that also detects errors. More advanced.
ハミング符号は誤り検出と訂正が可能です。
Hamming codes can detect and correct errors.
