Initially Wi-Fi is intended for the use of wireless devices and Local Area Networks (LANs), but currently more widely used to access the internet. How WiFi works the same as mobile phones, WiFi networks also use radio waves to transmit information over the network. the computer must include a wireless adapter that will translate data sent into radio signals. This same signal will be sent through the antenna for the decoder known as the router. Once translated, the data will be sent to the Internet via a wired Ethernet connection.
