What is wi fi ?
Wi-Fi is the name of a popular wireless networking technology that uses radio waves to provide wireless high-speed internet and network connections. A common misconception is that the term Wi-Fi is short for "wireless fidelity," however this is not the case. Wi-Fi is simply a trademarked term meaning IEEE 802.11x.
The wi fi alliance, the organization that owns the Wi-Fi (registered trademark) term specifically defines Wi-Fi as any "wireless local area network (WLAN) products that are based on the Institute of Electrical and Electronics Engineers' (IEEE) 802.11 standards."
Initially, Wi-Fi was used in place of only the 2.4GHz 802.11B standard, however the wi fi alliance has expanded the generic use of the Wi-Fi term to include any type of network or WLAN product based on any of the802.11 standerds, including 802.11b,802.11a, dual band ,and so on,in an attempt to stop confusion about wireless LAN interoperability.

How Wi-Fi Works?

Wi-Fi works with no physical wired connection between sender and receiver by using radio frequency (RF) technology, a frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space. The cornerstone of any wireless network is an access point (AP)The primary job of an access point is to broadcast a wireless signal that computers can detect and "tune" into. In order to connect to an access point and join a wireless network, computers and devices must be equipped with wireless network adapters

Wi-Fi Support?

Wi-Fi is supported by many applications and divecesincludingvidio game consoles, home network, major operating system, and other types of consumer electronic .any products that are tested and approved as "Wi-Fi Certified" (a registered trademark) by the WI FI alliance are certified as interoperable with each
