A digital subscriber line and a cable modem are two examples of broadband technology. DSL uses traditional copper wire telephone lines to transmit data. A cable modem transmits data using the same coaxial cable provided by cable operators to transport pictures and sound to a television.
There are two types of DSL technologies: asymmetrical digital subscriber line and symmetrical digital subscriber line. ADSL is predominantly used for residential customers, as it provides faster download speeds in comparison to the upload speed. SDSL is predominantly for businesses that require significant bandwidth for uploading and downloading data.
Both ASDL and cable modems have comparable speeds. However, a cable modem speed is influenced by the type of cable modem used and the network traffic. ADSL speeds are influenced by the distance between the premises and the telephone company facility exchange.
