Wireless Fidelity (Wi-Fi)
The popular term for a high-frequency wireless local area network. The consumer-friendly name for the 802.11b engineering standard. It lets home and office users create wireless local networks, which connect two or more computers to each other and a faster Internet line. This way there is no more poking holes in walls or tripping over bulky Ethernet cables. The Wi-Fi technology is rapidly gaining acceptance as an alternative to a wired local area network (LAN).
Well, it's a good one. Wifi is a way of surfing the net, using wave signals. It is also a general connection interface for most products used in gaming or security appliances(mainly or not). Some say it has an abbreviation in its letters, saying it may be an energy source, too. That's all.
