Wi-Fi, also, WiFi, Wi-fi or wifi, is a brand originally licensed by the Wi-Fi Alliance to describe the underlying technology of wireless local area networks (WLAN) based on the IEEE 802.11 specifications.
Wi-Fi was intended to be used for mobile computing devices, such as laptops, in LANs, but is now often used for increasingly more applications, including Internet and VoIP phone access, gaming, and basic connectivity of consumer electronics such as televisions and DVD players. There are even more standards in development that will allow Wi-Fi to be used by cars in highways in support of an Intelligent Transportation System to increase safety, gather statistics, and enable mobile commerce IEEE 802.11p.
A person with a Wi-Fi device, such as a computer, telephone, or personal digital assistant (PDA) can connect to the Internet when in proximity of an access point. The region covered by one or several access points is called a hotspot. Hotspots can range from a single room to many square miles of overlapping hotspots. Wi-Fi can also be used to create a Wireless mesh network. Both architectures are used in Wireless community network, municipal wireless networks like Wireless Philadelphia [1], and metro-scale networks like M-Taipei [2].
Wi-Fi also allows connectivity in peer-to-peer mode, which enables devices to connect directly with each other. This connectivity mode is useful in consumer electronics and gaming applications.
When the technology was first commercialized there were many problems because consumers could not be sure that products from different vendors would work together. The Wi-Fi Alliance began as a community to solve this issue so as to address the needs of the end user and allow the technology to mature. The Alliance created another brand "Wi-Fi CERTIFIED" to denote products are interoperable with other products displaying the "Wi-Fi CERTIFIED" brand.

Just a wireless (radio) connection from your laptop to a router. Mine has a built in Modem. So my laptop, I'm using in the kitchen connects to my router in my office wirelessly. It will also connect via the modem to the Internet - as it is now or I can connect to my desktop computer to send or receive files from that - and it also does printer sharing. if my printer was switched on - I could print from here - while cooking dinner - rather than having to go to my office. The communication is encrypted (in code) - so no one else can listen in. I'm also connected to the local school - but again they can't get my data and I can't get theirs - both are encrypted. There is another wireless router in range - maybe a neighbour - but that is encrypted or something - no use to me anyway!

Wifi is a local area network that uses high frequency radio signals to transmit and receive data over distances of a few hundred feet; uses ethernet protocol.
