Scenario#1: There is only one PC to connect to the Internet. In this case, you need the
network card and also the Cable/DSL modem that is provided by your Internet Service
Provider and a connecting cable (cable type needs to be verified with the ISP/modem
manufacturer. Some modems connect using a straight through cable and some require a
crossover cable) that would go between the computer and the modem.
Scenario#2: There are more than one computer to connect to the Internet through the
cable/DSL modem. In this case, assuming that you have the permission of your ISP for
sharing that cable/DSL line between several systems, you can use Internet Connection
Sharing (ICS)or an
Internet Broadband Gateway
, which basically allows LAN
connections to shares the connection to the Internet.
