What is one benefit of encryption in data security?

• A. Increases data transmission speed
• B. Prevents unauthorized data access
• C. Improves system optimization
• D. Boosts system memory capacity

Answer: (B)

One significant benefit of encryption in data security is that it prevents unauthorized data access. Encryption works by transforming data into a code or cipher, which can only be deciphered by those who possess the appropriate decryption key or password. This means that even if unauthorized individuals manage to access the data, they will be unable to read or use it effectively without the decryption key. This level of protection is crucial in safeguarding sensitive information, such as personal data, financial records, and proprietary business information, from cyber threats and breaches.

The other options provided do not accurately reflect the primary role of encryption in data security. For instance, while speed, optimization, and memory capacity are important factors in overall system performance, they do not pertain to the core functionality of encryption, which revolves around safeguarding data from access by unauthorized parties.
