Wi-Fi
Wi-Fi is a way of accessing networks and the internet without using wires using Radio waves. It is often found in smartphones, laptops and newer computers. To create a wireless network, a wireless router is needed.
Wi-Fi is a wireless brand owned by the Wi-Fi Alliance. Wi-Fi uses the IEEE 802.11 standard to send and receive information between computers. A Wi-Fi device will work anywhere in the world.
The word Wi-Fi is a pun on hi-fi and was invented to replace the old long name "IEEE 802.11b Direct Sequence Spread Spectrum".[1][2][3]
There are many different type of WI-FI ( IEEE 802.11 ) standards, some of the more commonly know ones are Wireless A,B,G,N and now the newly suggested AC & AD. The major difference between these standards is the distance which devices can connect the access points and the speed ( Bandwidth_(computing) ) in which these devices can go.
The World Health Organization (WHO) says that Wi-Fi is not dangerous.[4][5]
