Which of the following is an example of a security measure that personal devices might lack?

Enhanced encryption algorithms are considered a security measure that personal devices might lack because many consumer-grade devices prioritize user convenience and performance over advanced security features. While personal devices often include basic encryption methods, they may not implement the more robust and sophisticated encryption algorithms found in enterprise-level security solutions or specialized hardware designed for high-security environments. This lack of enhanced encryption can make personal devices more vulnerable to unauthorized access and data breaches, emphasizing the importance of adopting strong encryption practices for sensitive information.

In contrast, the other options focus on features that do not directly relate to security measures. Multiple user accounts can improve security by allowing different levels of access and accountability; faster processing speeds and large storage capacity are primarily performance and usability considerations rather than security-related features.
