To get the full effect of the Internet, and gain the most benefit from it, you need a broadband connection. Dial-up connections are not fast enough. The most popular ways to get broadband connections are TV cable systems, telephone DSL lines, satellite dishes, and cellular networks.
Cable TV companies deliver Internet connectivity through the same lines used to deliver your cable TV programs. Telephone companies deliver Internet connectivity through the same lines used to deliver your voice service. They use special lines called digital subscriber lines (DSL) that allow you to talk and transmit/receive data at the same time. Satellite companies deliver Internet connectivity wirelessly through satellite dishes like the ones used to deliver TV programming. Cellular companies deliver Internet connectivity directly to cell phones through the same wireless networks they use to deliver voice calls. For computers, you connect a device called a modem to the cable, telephone, or wireless drop and connect your computer to the modem.
