What does WiFi stand for?

WiFi stands for "Wireless Fidelity," which denotes a technology that allows electronic devices to connect to the internet or communicate with one another wirelessly. This term was coined to represent a suite of technologies and standards that facilitate wireless local area networks (WLANs) and ensure compatibility and ease of use among products from different manufacturers. The term "fidelity" in this context suggests a certain level of reliability and performance in the transmission of data over wireless networks, akin to the term “Hi-Fi,” which stands for high fidelity and is commonly used in audio systems to indicate high-quality sound.

The other options, while they may include relevant keywords, do not accurately represent the standard designation for WiFi. "Wide Fidelity" and "Web Fidelity" are not recognized terms related to wireless technology, and "Wireless Flexibility" does not encapsulate the intended meaning or usage of WiFi as it relates to network standards and technologies. Thus, "Wireless Fidelity" is the correct explanation for what WiFi stands for.
