explain wi-fi for me please?

Answer 1

It's a term for any wireless technology (Wi-Fi = wireless fidelity). You can connect to the internet using your portable device (laptop, for instance) but it has to be wi fi capable - there's a card you would need to have already installed, or you can add one. Mainly, people use it to access the internet in airports, etc..using their laptops.

Answer 2

Wi-Fi® (also WiFi, wifi, etc.) 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. It was developed to be used for mobile computing devices, such as laptops, in LANs, but is now increasingly used for more services, including Internet and VoIP phone access, gaming, and basic connectivity of consumer electronics such as televisions and DVD players, or digital cameras. More standards are 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 (see IEEE 802.11p). Wi-Fi® and the Wi-Fi CERTIFIED™ logo are registered trademarks of the Wi-Fi Alliance® - the trade organization that
tests and certifies equipment compliance with the 802.11x standards.

Wi-Fi
Short for wireless fidelity and is meant to be used generically when referring of any type of 802.11 network, whether 802.11b, 802.11a, 802.11g . . .
