What is "tethering"?

Tethering is the process of using a cell phone or smartphone as a modem for a personal computer of some sort - typically a laptop computer. The term gets its name from how a phone is attached, or tethered, to the computer via a USB cable, but wireless technologies such as Bluetooth can also be used for tethering. Typically the network carrier and the user's account (contract) have to support tethering before it can be used. Many networks charge an additional fee for users that wish to connect their phones as tethered modems because it typically uses far more data than using the phone normally would.
