Which of the following is also considered a usability factor for websites?

• A. Navigation
• B. Encryption
• C. Compression
• D. Latency

Answer: (A)

Usability hinges on how easily users can interact with a site, move around it, and complete tasks. The best choice is navigation because a clear, well-structured set of menus and links lets users find pages quickly, understand where they are, and move where they want to go without confusion. This directly reduces effort and frustration, which is the heart of usability.

Encryption is about protecting data and security, not how easy the site is to use. Compression and latency affect how fast things load and respond, which influences user experience, but they’re typically seen as performance considerations rather than core usability factors.
