1. High-speed cable Internet is a broadband technology from cable service operators (also known as multi-service operators - MSOs). This technology enables high-speed Internet access to the home over the standard television cable connection. Users can experience data transmission rates from a few hundred kbps to up to 30 Mbps, however, bandwidth significantly varies on a cable network since it is a shared medium. High-speed cable Internet is an open network, offering little security to users who connect directly to the cable connection without a cable/DSL firewall/router device.
