there are difference between broadband cable DSL and fiber.

cable DSL and fiber

the difference between broadband cable, DSL, and fiber. Now cable internet is a high-speed access technology that uses a cable modem with  an attached coaxial cable which provides a link to the internet service provider. Broadband cable  is typically provided by the same provider that provides cable television to their customers.  And because it's provided by cable television providers, broadband cable leverages the  existing infrastructure from cable TV to cover large geographical areas especially here in the  United States. Today if you want broadband cable, your provider offers different packages that vary  in speed. So for example I use broadband cable  from Xfinity and they offer download speeds  anywhere from 25 Mbits/s all the way up to  400 Mbits/s. So if you were to order cable  internet for your home, your cable internet provider would send you a modem or typically they  would send you a modem with a Wi-Fi router combo, which is often referred to as a gateway. And this  device would be a modem with a built-in switch and  Wi-Fi router all in one. So when you receive this  modem from your ISP, you would attach a coaxial  cable that's routed into your home and then you  would attach it to the back of the device. The  modem is what brings the internet into your home  and the switch and the Wi-Fi router is so that  you can connect multiple wired and wireless  devices, such as computers, laptops, tablets, to the modem to give them internet access. And that's basically it, now cable does have

a downside and that's because you, along  with the other homes in your neighborhood, will all have to share a pool of bandwidth that's  been provided by your cable provider in your area.  what that basically means is that during  peak hours of surfing the internet or streaming or downloading, you may experience a slowdown in  your internet speed. And that's because the people in your neighborhood are all using the internet  bandwidth. Now DSL stands for a digital subscriber  line. DSL is another popular technology that is  used by homes and businesses to access broadband  data over the internet. DSL can carry both voice  and data at the same time over phone lines. It has a DSL modem like this one here, that uses  common telephone lines to carry its data. And because DSL uses phone lines, you don't want to  confuse DSL with the older and painfully slow dial-up connection which also uses phone lines.  DSL is a high-speed connection that is much faster than the ancient dial-up connections. And with DSL  you can go on the internet and talk on the phone at the same time, unlike a dial-up connection  where you can only do one at a time. Now DSL is not as fast as cable but it is cheaper. And also  with DSL you don't have to share bandwidth with your neighborhood like cable does. Everyone using  DSL has their own dedicated connection. It's not a shared line. And DSL is more widely available  than cable because it uses common telephone lines which are nearly everywhere. Now the speed of DSL  can vary depending on where you live. But on an

average, they offer download speeds anywhere from  5 Mbits/s up to 100 Mbits/s. And just like cable, when you order DSL through a provider, they will  also send you a DSL modem Wi-Fi router combo. But instead of attaching a coaxial cable, you would  plug a typical phone line with a phone jack to the back of a DSL modem. Now there are a few  different forms of DSL. And one is called ADSL which stands for asymmetric digital subscriber  line. Now this is called asymmetric because the download speed is considerably faster than the  upload speed. This type of DSL is mainly used in homes because home users typically download a  lot more than upload. And ADSL is the cheapest form of DSL And there's also SDSL which stands  for symmetric digital subscriber line. And this, as a name implies, the download and upload speeds  are the same. And this type of DSL is typically used in businesses. And finally there's VDSL  which stands for very high bit DSL. And this is  a fast form of DSL that also runs over copper wire.  And because it uses copper wire it's really only made for short distances. For long distances, it can  also use fiber optic cable. VDSL is roughly three times faster than ADSL. And finally there's fiber  internet. Fiber offers the fastest internet speeds  available today. It has download and upload speeds  of 1000 Mbits/s, so it's very fast. And the reason why it's so fast is because it uses  light to send data running through fiber optic cable . And fiber optic cable is what's already used  as the backbone of the internet. And in addition to  the benefit of the faster speed, fiber can also  travel much longer distances than DSL or cable. And this is because DSL and cable transmit data  using electricity over copper cable and signals in a copper cable can be affected by electromagnetic  interference as it travels which can weaken the signal especially over a long distance. But fiber  uses light to transmit its data and it transmits it over a thin glass cable which makes it less  vulnerable to interference. So as you might have guessed, fiber is more expensive than DSL or  cable and fiber is relatively new compared to DSL or cable. The infrastructure is not there yet.  So fiber may not be available in many locations,
