Which term is used for the process of turning plain data into cipher text?

• A. Encryption
• B. Electronic Penetration
• C. DHCP
• D. Domain

Answer: (A)

Encryption is the process of turning plain data into cipher text using algorithms and keys to conceal the information. This transformation makes the data unreadable to anyone who doesn’t have the proper key to decrypt it back into its original form. Decryption is the reverse process, recovering the plaintext from the ciphertext. The other terms don’t describe this transformation: electronic penetration isn’t a standard term for turning data into unreadable form, DHCP is a protocol for dynamically assigning IP addresses, and a domain refers to a naming space rather than a data-protection process. Encryption is essential for keeping data confidential in transit and at rest.
