Which term is a numeric code used to identify the type of error in data transmission or any other system errors?

• A. Error codes
• B. Error checking
• C. Encryption
• D. Domain

Answer: (A)

Error codes are numeric labels that identify the exact type of error reported during data transmission or by a system. They provide a concise, standardized way for software to understand what went wrong and how to respond, such as retrying, alerting a user, or logging the issue. Error checking, by contrast, describes mechanisms (like parity, checksums, or CRC) that detect that an error has occurred, but not the specific kind of error. Encryption focuses on protecting data confidentiality, not labeling errors, and domain is simply a naming space for resources, not a way to describe error conditions.
