The other day at the gym, the T.V. was on BNN channel and they were discussing Apple's iphone 5. The two news reporters were impressed by the gadget's features; while expressing their fondness for various features of the phone they kept incorrectly interchanging Internet with WiFi.
Internet is not the same as WiFi!
It is incorrect to say we [cannot] connect to WiFi. We can connect to Internet, a group of computers connected together, via WiFi, technology that allows any computer with wireless network interface controller to connect to another through radio frequency and without using any wire.
