What does "data encryption" do?

• A. It decodes data for easier access
• B. It converts data into a coded format to prevent unauthorized access
• C. It compresses data to save space
• D. It makes data publicly accessible

Answer: (B)

Data encryption is a security process that transforms information into a secure format that is unreadable to unauthorized users. When data is encrypted, it is converted into a coded version using algorithms and encryption keys, ensuring that only those who possess the correct key can access the original information. This process helps protect sensitive data from cyber threats, data breaches, and unauthorized access. By converting data into a coded format, encryption serves as a critical defense mechanism in safeguarding personal, financial, and confidential information from malicious actors. It is an essential aspect of data security in various fields such as finance, healthcare, and information technology.
