Some DSL internet service providers, like Yahoo, give parents a number of ways to control access to the account. In many ways, technology makes room for increased communication between individuals but it can also be the cause of miscommunication and a lack of communication altogether. An unbelievably cheap DSL internet service, one that is too good to be true, could be exactly that, too good to be true. Again, some, like Yahoo, will include one with your account.

When the telecomms decided to add DSL availability to the same copper wires, they opted to use frequencies in the 4,000 Hz and up range. However, in many places you can't choose DSL vs cable. If you've been online for several hours before noticing any drop in speed, then try turning off both the computer and router for at least 30 minutes to let the equipment cool down. Those of us who are familiar with dial-up will not see any difference in their homes besides a modem box and a faster internet connection. One important thing that you should know before you make your own choice is that when you install your own hardware, you will not be able to avail yourself of any technical support from your ISP provider - which can be a pretty bad setback. Adding additional email addresses or IP addresses will raise the bill.
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.
