wireless networking technology known a second name of wifi. Wifi uses radio waves to provide wireless high-speed Internet and network connections.
The term “Wi-Fi” suggests “Wireless Fidelity”, comparing with the long-established audio recording term “Hi-Fi”, and “Wireless Fidelity” has often been used in an informal way, even by the Wi-Fi Alliance itself, but officially the term does not mean anything.
The name of a popular wireless networking technology that uses radio waves to provide wireless high-speed Internet and network connectionWi-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 the 802.11 standards, including 802.11b, 802.11a, dual-band, and so on, in an attempt to stop confusion about wireless LAN interoperability.
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.
Wi-Fi is supported by many applicationsn and devices including video game consoles, home networks, PDAs, mobile phones, major operating systems, and other types of consumer electronics
