Which statement best describes encryption?

• A. Process of converting data into compressed form
• B. Conversion of data that cannot be easily understood by unauthorized people
• C. Process of removing data from a system
• D. Storage of data in cloud

Answer: (B)

Encryption is the process of transforming readable data into a form that is unreadable without the correct key. This protects confidentiality by ensuring that even if someone intercepts or gains access to the data, they cannot understand its contents without the decryption key. It's not about reducing data size through compression, deleting data, or simply storing it somewhere; its purpose is to conceal meaning so unauthorized parties cannot comprehend the information.
