What is a system used for connecting computers and other electronic equipment to the internet called?

Wi-Fi is a way of connecting to a computer network using radio waves instead of wires. It was invented to connect computers that are near each other, and nowadays is much used for Internet connections.

Wi‑Fi is a trademark of the non-profit Wi-Fi Alliance. The name Wi-Fi, commercially used at least as early as August 1999, was coined by the brand-consulting firm Interbrand. The Wi-Fi Alliance had hired Interbrand to create a name that was "a little catchier than 'IEEE 802.11b Direct Sequence'." Phil Belanger, a founding member of the Wi-Fi Alliance, has stated that the term Wi-Fi was chosen from a list of ten potential names invented by Interbrand.

The name Wi-Fi has no further meaning, and was never officially a shortened form of "Wireless Fidelity".

Interbrand also created the Wi-Fi logo. The yin-yang Wi-Fi logo indicates the certification of a product for interoperability.
