DSL technology allows you to surf the Internet and download files to your computer with amazing speed. You'll be able to play network games with relative ease. And streaming audio and video are becoming popular applications for DSL Internet service. Unlike the dial-up connections required for analog modems, your DSL connection is always on. That means no more logging on and off, no more busy signals and no more waiting for the connection to happen - it's always there.
Cable modems offer always on high-speed Internet access over a shared cable television line.
Shared bandwidth causes slowdowns. Cable modem services usually do not support a wide variety of Internet applications.
