One of the advantages of DSL over cable modems is that the line to the exchange or “switch” is not shared.Both cable and DSL services have a cap on bandwidth. Look for the green (in Toronto) phone exchange box in your neighbourhood and note how far your home is from that box.The first cap is on data transferred per service period (usually per month).What exactly are the differences between Cable and DSL Internet services?First let’s define our terms.
So bandwidth is a measure of frequency or a rate of service delivery while latency is a measure of time or signal delay.Cable service uses signals transmitted through the same coax cable that cable television uses.. As a result the performance is quite similar to DSL. Both DSL and Cable companies limit bandwidths at both the modem level and at the service provider. The distance to your exchange or “switch” is the main factor that determines DSL quality of service. DSL uses normal phone lines to send digital signals to a DSL modem.DSL service usually provides a more constant, consistant feed, with lower latency.Generally, cable modems can achieve better peak throughput, but this high bandwidth is not consistant and depends, again, on load, affected by time of day and other factors.com.
This means that you will generally be able to sustain a certain bit rate while downloading or receiving data and a different bit rate while uploading information.If you are shopping around for a service or thinking of changing services, the best advice I have for you is to ask other users about their service. One of the best web sites I’ve seen for sharing this data is broadbandreports. Your data cap may be as little as 1 gigabyte per month or, in the case of most cable modem services, unlimited.In general, because of the far greater capacity of coaxial cable and the fact that only a certain number of lines exist connecting you to your switch, cable modems, if uncapped would provide advantages in bandwidth over DSL modems. Though ISPs trying to sell DSL services will tout this as a major advantage, slow cable modem speeds have very little to do with this and have much more to do with the fact that cable service is shared among many users and services. This includes the time it takes for an electrical or optical signal to travel a certain physical distance (propagation delay) and the time it High Pressure Snap-in Tubeless Rubber Valves factory takes to process these signals along the way (processing delay).
But, the coaxial cable coming into your home is shared with many people outside your house and provides many services.Shop Around.Bandwidth vs.This site provides user-submitted reviews of their broadband service and charts day-to-day service fluctuations.Technology Comparision. Speed tests and other tools for optimizing your connection are available as well. Your service provider may promise you a certain downstream limit and a certain upstream limit. From my experience, DSL data transfer caps are more rigidly controlled than cable services.Coaxial cable has a far greater capacity than RJ-11 phone cable.Cable modems have higher bandwidth though the connection is shared among cable users in your service area and even with your digital cable box. Latency:Bandwidth & ThroughputDigital bandwidth or throughput is a measurement of the amount of data that can be transferred over a digital line over a specific amount of time.ISPs tend to enforce a bandwidth cap on both DSL and cable modem services.LatencyLatency is the time it takes to deliver a packet of data from one place to another. In the real world, this is not the case
