gzt: What you are looking for is called reverse tether (with usb support). There are many apps available for this, and my guess is all will require rooting.
You could also consider Bluetooth. Shorter range, lower power, lower power consumption.

mrplane: Hi everybody, was wanting to know if it is possible to connect a samsung tablet or an ipad to the internet with a cable rather than wifi?
