Definition:
WiFi -- or, more accurately, "Wi-Fi" -- is a type of wireless networking protocol that allows devices to communicate without cords or cables. Wi-Fi is technically an industry term that represents a type of wireless local area network (LAN) protocol based on the 802.11 IEEE network standard. It's the most popular means of communicating data wirelessly, within a fixed location, today.
"Wi-Fi" is a trademark of the Wi-Fi Alliance, an international association of companies involved with wireless LAN technologies and products.
Wi-fi is commonly mistaken as an acronymn for "wireless fidelity" and often you may also see it spelled without the hyphen (wifi).
Also Known As: wireless, though the term wireless is actually much broader
Alternate Spellings: wifi, WIFI, WiFi
Examples:
There are many wifi hotspots available to the public today where they can access free or paid wireless networks for Internet access or file sharing, including airports, hotels, Starbucks, Panera Bread, and others.
