From Week 9 Research – The Difference Between Broadband and DSL.

The word “broadband” is used for any internet service that provides a continuous (always on) high-speed internet connection. DSL, which stands for digital subscriber line, is also a “broadband” connection. There are, however, different types of broadband connections that use different wiring and transmission systems to connect users to the internet. These different types are DSL, cable, fiber optic, wireless, and satellite. DSL internet uses telephone wiring to connect users to the internet. It sends data from the computer’s telephony modem to the internet service provider’s modem over the telephone lines in digital form. Cable broadband internet uses coaxial cables to transmit data from the computer’s modem to the internet service provider’s modem. Speed and quality are similar to that of DSL, though throughout history DSL speeds have been slower. Fiber-optic broadband internet uses wires made of plastic or glass to transmit data from the internet service provider to the computer. The data travels through these wires as light granting greater download and upload speeds than any of the other broadband internet types. While DSL and cable broadband internet uses wires that are already installed in the home or business, the fiber-optic broadband internet service require the installation of this type of wiring. Wireless broadband internet does not require the use of wires. It uses radio waves that transmit data from the internet service provider to the user via a wireless card installed in the computer. This type of connection is typically on a cable, DSL, or fiber-optic broadband and the signal is broadcasted. Satellite broadband internet transmits data from satellites to a dish outside the home or building. The dish is connected to sending and receiving equipment and then connected to the user’s modem. This type of internet is typically used in remote areas where there are no other internet options available.
