N: 1. It dates back to 1999, a common misconception is that it is short for ‘wireless fidelity’. ‘Wi-Fi’ is simply a trademarked phrase that means IEEE 802.11x.
2. It is a wireless networking technology that uses radio waves to provide wireless high-speed Internet and network connections.
3. 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’.
4. Like mobile phones, a Wi-Fi network makes use of radio waves to transmit information across a network. The computer should include a wireless adapter that will translate data sent into a radio signal. This same signal will be transmitted, via an antenna, to a decoder known as the router. Once decoded, the data will be sent to the Internet through a wired Ethernet connection. The wireless network works as a two-way traffic, the data received from the Internet will also pass through the router to be coded into a radio signal that will be received by the computer’s wireless adapter.
