Whether at work or at home, you get onto the Internet via a variety of ways. You may connect to a LAN at your place of business via Ethernet networks and token-ring networks. Token-ring networks pass data in tokens from computer to computer in a ring or star configuration. In Ethernet networks, the data goes from a server to a computer on the network. At home, you can dial into a large computer connected to the Internet via an online service or a dial-in Internet service provider (ISP), or you can use another type of Internet service, such as a cable modem, Digital Subscriber Line (DSL) modem, or a satellite connection.
