Router A gadget that receives and analyzes packets and then routes them towards their destination. multiple hosts collectively and forwards packets based mostly on their vacation spot inside the native community which is often often known as a Local Area Network . Packet The elementary unit of information transmitted over the Internet.

Wi-Fi takes an Internet signal and converts it into radio waves. These radio waves can be picked up within a radius of approximately 65 ft by devices with a wireless adapter.

Several Wi-Fi specs have been developed over the years, starting with 802.11b in 1999, followed by the 802.11g specification in 2003 and 802.11n in 2009. Each new specification improved the pace and vary of Wi-Fi, permitting for extra uses. One of the first places where Wi-Fi is getting used is in the residence.
