Define "encryption."

• A. The method of transferring files over the internet
• B. Converting information into a code to prevent unauthorized access
• C. A process to increase internet connection speed
• D. Creating backups of important files

Answer: (B)

Encryption is the process of converting information into a code to prevent unauthorized access. This transformation is crucial for securing data, especially when it is transmitted over networks or stored on devices. By converting readable data into an unreadable format, encryption ensures that only those with the appropriate decryption key or password can access the original information. This technique is widely used in various applications, including online banking, communication, and data storage, to protect sensitive information from potential threats, such as hackers or identity theft.

The other options do not accurately capture the essence of encryption. Transferring files over the internet pertains to data transfer methods rather than securing data. Increasing internet connection speed is related to network performance, while creating backups of important files focuses on data preservation rather than security. Thus, only the definition involving converting information into a code aligns with the true meaning of encryption.
