What does dsl function?

Answer 1

DSL stands for digital subscriber line. DSL providers use the technology to provide high speed access to the internet.

DSL works through the use of telephone lines. However, unlike dial-up internet, the previous option available, DSL can be used at the same time as the telephone. This is possible because the DSL and the telephone signals use different parts of the same copper line.

This can be accomplished because both signals go through the line at different frequencies. The information sent back and forth through the line for the DSL internet access will use a high frequency. Alternatively, the information sent through the line for phone calls will use a low frequency. This way the frequencies do not intermix, causing neither to fail while they are being sent at the same time.

This was a massive improvement over the previous “dial-up” technology that did not allow phone calls to be made at the same time the internet was being accessed. DSL was also a massive improvement compared to dial-up in terms of download speed. DSL download speeds can range from one megabyte per second to three megabytes per second. Dial-up, on the other hand, can be as slow as fifty six kilobytes per second. That’s a big difference.

The speed of DSL internet is also maximized by the fact that downloads and uploads are sent through different parts of the cable. The space in a telephone cable will allow for both upload and download signals to be sent down the cable in both directions at once. However, the space generally allowed for downloads is much larger than the space used for uploads. This is because most web surfers generally use their internet service more for downloading than uploading. Clicking on internet links, for example, takes up very little upload bandwidth space.

These kinds of lines where the download speed is much great than the upload speed are known as ADSL lines. However, for people who need much higher upload speeds, there is the option of using SDSL lines. SDSL lines are DSL lines that have the same quick speed for both downloading and uploading files

While DSL has many great attributes, cable internet may actually be faster in most cases. However, cable internet is not available everywhere, making DSL providers the choice used by millions of internet subscribers.

Answer 2

A DSL provider uses the phone lines, though not the specific lines that are actually used by the phone service, in your home to bring the service into the house and to your computer. Data is then transfered in and out by way of the phone lines.
