Wi-Fi is a standard wireless networking technology that allows computers and other electronic devices to communicate with each other remotely. When a product has the Wi-Fi label, it is certified to work with standard wireless networking devices.
The term Wi-Fi was coined in 1999, with the "Wi" apparently standing for wireless. It is suggested that the "Fi" is a play on the term "Hi-Fi," or high fidelity, but the "Fi" in Wi-Fi does not stand for fidelity and was simply the name chosen by the Wi-Fi Alliance. The Wi-Fi Alliance is a global non-profit association of companies that control Wi-Fi products and services.
