Ethernet is a means of connecting to the Internet.
It does not use phone lines or a modem. Ethernet is MUCH faster than any kind of dial-up service available making file transfers much more convenient. Also, as it does not tie up your phone line, you can browse the internet and talk on the phone simultaneously. There is no monthly charge for Ethernet access here at Southern Adventist University. The only cost to the student is that of an ethernet card, a cord, and setup.
