Throughput is the amount of data that can be transferred over your Internet connection at one point in time.
Kbps or kilobits per second is the rate at which a kilobit (1,000 bits) of data travels across your Internet connection. A bit is the smallest unit of digital information. Eight bits make up one byte.
The test shows the current throughput you can get on your Internet connection. Factors such as network congestion and other downloads in progress can affect the available throughput.
The results of the test can be affected by any network congestion between you and our servers. If you have other downloads in progress this can also affect the results.
We calculate the speed of your Internet connection by calculating the time it takes to download a predefined set of data.* Actual speeds may vary based on factors such as line quality, distance from exchange (for ADSL/ADSL2+), technology used, hardware capabilities, server route, and network congestion.
