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).
This error-detecting code ensures data integrity.
Loanword version using エラー (error) and コード (code). Common in IT contexts.
We need to implement an error-detecting code.
More explicit: 'code for error detection'. Less common but still valid.
Designing an error-detecting code is complex.
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.
Parity check codes can detect single-bit errors.
Cyclic Redundancy Check code. Widely used in networks and storage.
CRC codes are robust against burst errors.
Checksum, a simple error-detecting method. Often used without 符号.
Hamming code, an error-correcting code that also detects errors. More advanced.
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).
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 codes can detect and correct errors.
