Cable Vs DSL

The maximum amount of data that can be transferred using the latest modem is less then 56 Kbps (thousands of bits per second). "The ability of your computer to receive information is constrained by the fact that the telephone company filters information that arrives as digital data, puts it into analog form for your telephone line, and requires your modem to change it back into digital. In other words, the analog transmission between your home or business and the phone company is a bandwidth bottleneck."1 Digital Subscriber Line technology assumes that it is not necessary to convert the signal from digital form into analog and back. Digital data is directly transmitted to your computer thus allowing the phone company to use a much wider portion of the available bandwidth. Nevertheless, you, as the consumer, can choose the signal to be separated thereby some of the bandwidth is used to transmit an analog signal allowing you to use your telephone and computer simultaneously on the same line. .
             Currently there are a number of different variations of DSL available to the average consumer. The most common option for a home and small business user is called ADSL, or Asymmetric Digital Subscriber Line. "ADSL is called "asymmetric" because most of its two-way or duplex bandwidth is devoted to the downstream direction, sending data to the user." Only a small part of the bandwidth is available for uploads or sending information from the user out to the Internet. ADSL allows up to 6.1 Mbps of data for download and up to 640 Kbps for upload. The high download bandwidth will enable your telephone line to bring motion video, audio, and 3-D images to your computer or TV set. Additionally, a small section of the bandwidth can be dedicated to voice communication; this will allow a person to talk on the phone without requiring a separate analog line.
             Another common type of DSL is the SDSL.
