What is Wi-Fi?

Wi-Fi refers to Wireless Networking Technology that allows computers and other devices to communicate over a wireless signal. 

Does the word WI-Fi have a meaning?  Some says it is short for "Wireless Fidelity.” It describes all network components that are based on one of the 802.11 standards, including 802.11a,802.11b, 802.11g, and 802.11n. These standards were developed by the IEEE and adopted by the Wi-Fi Alliance, which trademarked the name "Wi-Fi".

Wi-Fi is the standard way computers connect to wireless networks. Areas which are enabled with Wi-Fi connectivity are known as Hot Spots. It can either be through a closed wireless network at home or in public places like restaurants or airports. To access this type of connection, one must have a Wireless Adapter on their computer.
