What is the goal of data encryption?

• A. To enhance data transfer speed
• B. To protect data confidentiality by encoding it
• C. To store data for long-term access
• D. To simplify data retrieval processes

Answer: (B)

The goal of data encryption is to protect data confidentiality by encoding it. Encryption transforms readable data into an unreadable format using algorithms and keys, ensuring that only authorized parties who possess the correct key can access the original information. This process is essential in safeguarding sensitive information from unauthorized access, ensuring that it remains confidential and secure during storage or transmission.

While enhancing data transfer speed, storing data for long-term access, and simplifying data retrieval processes may have their own merits in various contexts, they are not the primary objectives of data encryption. Encryption specifically aims to secure the information itself, protecting it from potential breaches and ensuring that privacy is maintained.
