I am in search of some information and great discussion regarding WIFI.

Why it is called WIFI ?
Is it secure as compare to LAN ?
Cost Factor?
 
WiFi is the wireless network. Just as the mobile phones, tv uses the radio waves in the same it works using the radio waves. A computer's wireless card converts data into a radio signal and transfers it using an antenna then the router gets the signal and decodes and send information to the internet using wired Ethernet connection.
