"WiFi" is the common term applied to wireless internet access. Generally speaking, wifi involves the use of a wireless Cable or DSL router. This is generally supplied by your internet service provider, which is usually your phone company or cable company - or maybe both. The router connects to the cable coming into your house or business and then broadcasts a signal that computers and other devices (like some smart phones and iPads) can connect to. This way there is no need to connect a cable to your computer to access the internet. These days there is lots of "public" wifi which can be accessed at places like airports, hotels, Starbucks and Paneras. It may be free or you may be charged a daily fee.
