Almost everyone has heard of DSL, but how many know exactly how it works? As far as most folks are concerned, as long as the latest Lindsay Lohan gossip gets to them a split second after they type the phrase into Google, their high-speed internet is working as well as it needs to be. But what is happening in all of those tubes and how does that information get to them so quickly?
Since Digital Subscriber Line, or DSL, internet comes through the telephone lines, all of that information is traveling over copper wires. These wires are far more conductive than necessary for simple voice communication and DSL internet takes advantage of the extra room in the wires to send massive amounts of information without buy rx drugs without prescription disrupting the normal functions of a telephone line. This extra space is possible since the range of frequencies at which the human voice can speak is a fraction of the frequencies at which information can travel along copper wires. By utilizing these unused frequencies, DSL service is able to send a lot of information along an existing infrastructure of wiring.
Another secret to DSL’s lightening fast internet speeds is the way it is set-up. Most computers are connected to an asymmetrical DSL line; this type of connection assumes that the user will be downloading far more than they will be uploading and assigns frequencies as such. This makes the entire network run both faster and smoother.
All of this information enters and leaves the user’s home through a modem. This piece of technology assigns and divides the analog voice communications and digital internet information along the various frequencies. It routes everything to the proper channel and helps to direct the flow of the information. This ensures that everything is headed to the correct place and that no service is disrupted when the phone rings.
