What is WIFI and how does it work?

What+is+WIFI+and+how+does+it+work%3F

WiFi is a network that uses a radio frequency signal instead of wires to connect your devices to the Internet. WiFi signals can be picked up by any wireless-capable device within a certain distance in all directions. 

Recently, wireless technology has widely spread and you can get connected almost anywhere. 

Like mobile phones, a WiFi 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.

The radio signal will then be transmitted, via an antenna, to a decoder known as the router. Once the router gets the signal, the data will be sent to the Internet through wired connections.

As the wireless network transmit information, 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.
