Wi-Fi
Stephanie Gruss

Wi-Fi is an abbreviation for wireless fidelity. It is a wireless network that uses radio waves to allow users to connect to the internet. Wi-Fi is relatively inexpensive and easy to set up. Most find it a great alternative to a hard wired connection. An area where Wi-Fi is available is referred to as a "hotspot". These wireless networks can be closed meaning it is password protected or open meaning anyone can use it. Most public "hotspots" are open, but it is recommended that you protect your home or business wireless network with at least a password.
Wi-Fi is increasing popular. In fact, newer model laptops usually come with wireless cards built in so they are ready to use with Wi-Fi. If a laptop or other device does not have a wireless card an adapter is required to connect. The wireless card or adapter sends signals to the router. The router deciphers the signal and then send the information to the internet. Many large cities are even looking into providing city-wide Wi-Fi available for everyone.
