The History of DSLDSL, or 'digital subscriber line', is that handy set of technologies that allows you to browse the internet at warp speed. Spyware hogs your computer's processing power, while the cache takes up space that could be used to temporarily store web pages to let your hard drive access them faster. In the end, a DSL router is a beneficial and powerful tool that a company can utilize for maximum benefits. Speed is dependent on a host of other factors such as bad wiring, malfunctioning hardware, bad connections and so on; however, when it comes to the wireless DSL router the hardware and the wires are rarely the problem.

Let us look at a few major differences to compare DSL vs cable modem networking. Using the internet means putting your computer system at risk of viruses, most of us have virus protection of some kind on our computer. With DSL becoming more popular, many local ISP providers are offering you their service at reduced rates in comparison to the providers in the past. First, think about whether to go with one of the large DSL service providers, like AT&T, or whether a smaller local company would better suit you.
Joining the world of high-speed internet access can be like getting lost in a strange country where you don't speak the language: IP, ISP, DSL, an endless stream of acronyms. In order, that's: internet protocol, internet service provider, and digital subscriber line!
Broadband DSL, on the other hand, is refreshingly straightforward. Think of dial-up internet service as trying to run a lot of water through a small pipe. Now take that same amount of water and toss it through a pipe as big around as a garbage can. That's broadband DSL.
Ok, I lied. Broadband DSL isn't that straightforward and there are some acronyms involved. I'll explain them below.
ADSL
If you have broadband DSL at home you most likely have this flavor. The 'a' stands for asymmetric. All this means is that downloading content (reading an email) from the internet is about three times as fast as uploading (sending an email, for example).
DSL providers set their networks up this way because studies have shown that it's the best way to optimize the speed of their connections. The speed of an ADSL broadband service ranges from 400 to 700 kilobits per second downstream, and 100 to 350 kilobits per second upstream.
SDSL
You can probably guess now what the 's' in SDSL stands for - symmetric. Businesses prefer broadband DSL that sends data up and down stream at equal rates, so you're likely to find this species of broadband hiding out at the office.
Depending on the broadband DSL provider data flies through these wires at up to 1.54 megabits per second.
IDSL
This is an acronym buried within an acronym. The 'I' stands for 'ISDN', which in turn stands for 'Integrated Services Digital Network.' Put that together with DSL and you get the redundant 'integrated services digital network digital subscriber line.' What a mouthful. Let's just stick with the acronym.
Broadband DSL providers turn to IDSL when dealing with customers who live far from the telecomm's home office. Digital signals typically degrade with distance. The other types of DSL peter out around 18,000 feet.
That's where IDSL comes in - its reach extends more than twice the distance of SDSL, since it uses fiber optic technology instead of the pre-existing copper wires used by the other types of DSL and regular phone lines. One broadband DSL service provider will usually offer all three flavors of broadband.
