Which of the following describes data encryption?

Data encryption is accurately described as the process of encoding information to protect it from unauthorized access. This technique transforms readable data into an encoded format that can only be interpreted by someone who has the appropriate decryption key. Encryption is crucial in safeguarding sensitive information, ensuring that even if data is intercepted during transmission or accessed by unauthorized users, it remains inaccessible and secure.

This process is essential for maintaining data confidentiality and integrity, particularly in environments where sensitive personal, financial, or corporate information is handled. By using encryption, organizations can comply with various regulatory standards and protect their data from breaches or unauthorized access.

The other options do not represent the function or purpose of data encryption. Improving internet speed, enhancing accessibility, and monitoring network traffic are unrelated to the fundamental concept of data encryption, which centers on the security and protection of information through encoding.
