Encryption techniques are generally used to improve the_________of computer networks.Select one:ReliabilityPerformanceLongevitysecurity

Break Down the Problem

1. Identify the context of the question, which is encryption techniques in computer networks.
2. Consider the options provided: Reliability, Performance, Longevity, Security.

Relevant Concepts

1. Encryption enhances security by protecting data during transmission.
2. While it may impact performance due to processing overhead, this is not its primary purpose.
3. Reliability and longevity do not directly relate to encryption concepts.

Analysis and Detail

1. Security: The main role of encryption is to secure sensitive information from unauthorized access, thus making computer networks safer.
2. Performance: Although encryption may affect performance negatively, improving it is not a goal of encryption techniques.
3. Reliability and Longevity are broader concepts in network design and do not align with the primary function of encryption.

Verify and Summarize

• The question specifically asks for what encryption techniques improve, and the most aligned term here is security. Therefore, we can conclude that encryption techniques serve to enhance security in computer networks.

Final Answer

The correct answer is security.
