Which term describes the process of transforming data into a secured code based on an algorithm or established rules?

• A. Encryption
• B. Dynamic IP
• C. Error checking
• D. Domain

Answer: (A)

Encryption is the process of transforming data into a secured code based on an algorithm and a key. It turns readable data into ciphertext so that only someone with the correct key can revert it back through decryption, preserving confidentiality whether the data is stored or transmitted. The idea hinges on applying established rules (the algorithm) to scramble the data in a way that hides its meaning from unauthorized viewers. Dynamic IP is about how devices get IP addresses that can change, not about hiding content. Error checking verifies data integrity to detect corruption, not to conceal information. A domain refers to the DNS system that maps names to IP addresses, not to encoding data.
