Which term refers to techniques used to detect errors in data transmission, such as Parity check, CRC, checksum?

• A. Error checking
• B. Error codes
• C. Dynamic DNS (DDNS)
• D. Eavesdropping

Answer: (A)

Techniques used to detect errors in data transmission rely on adding redundancy to the data so the recipient can verify integrity. Parity checks, CRC, and checksums are classic examples of that approach. The term that encompasses these methods is error checking, which specifically covers detecting whether transmitted data has been corrupted. This isn’t about error codes, which are specific signals or messages indicating an error, nor about Dynamic DNS, which maps domain names to IP addresses, or eavesdropping, which is listening in on communications.
