A Wifi connection is established using a wireless adapter to create hotspots areas in the vicinity of a wireless router that are connected to the network and allow users to access internet services. Once configured, WiFi provides wireless connectivity to your device by emitting frequencies between 2.4GHz - 56GHz, based on the amount of data on the network.

Wireless networking is know as WiFi or 802.11 networking as it covers the IEEE 802.11 technologies. The major advantages of Wifi is that it is compatible with almost every operating systems, game devices and advanced printer.
How Wifi Works?
WiFi networks makes use 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 know as the router. Once decoded, the data will be sent to the internet through a wired Ethernet connection. As the wireless networks works as a two-ways traffic, the data received from thee internet will also pass through the router to be coded into a radio signal that will be received by the computer wireless adapter.
