Our speed test or calculates the speed of your connection, that is helps you know the speed of internet at home. The speed test is performed by a data download to your computer that allows the calculation of download time. Then a calculation of the upload speed of your connection is made.
Any Internet users can easily perform the test.
It is generally speaking the broad-band access network, ie the final link between the client and the network.
Technology Access Network
Fiber to the customer's home (technically FTTH, fiber to the home), highly developed in certain countries (Japan, South Korea ...)
The coaxial cable, historically introduced by cable TV providers, present mainly in certain urban areas.
The artificial satellite, which has a constant speed downstream (receive data), but with significant delays limiting real-time applications such as voice over IP or video game online.
DSL, asymmetric systems (check ADSL) or other (xDSL) are technologies that leverage the copper pair of traditional telephone network.
Power Line Communications, which use electrical distribution network.
These techniques are capable in theory provide multiple services (voice, data, video) at high speed but, in practice, service quality is variable. Geographical distance weakens the signal (except in the optical fiber transmission) and most access technologies are likely to offer lower rates if the customer is away from the central office.
The performance of a connection is never 100%. Keep in mind that different protocols (PPP, TCP / IP) occupying bandwidth (between 2% and 20% 100% used in these types of connections (optical fiber, cable, ADSL, etc) total, the connection type, protocol used), thereby width useful for downloading data band is reduced.
The results shown in this test corresponds to the useful bandwidth, this is equivalent to the speed of information transfer, and not the access speed. Additionally, other unmeasured factors that may contribute to reduce the speed of the connection, such as network congestion, electromagnetic interference, etc., also influence the final result.
