This is a list of countries by Internet connection speed for average and median data transfer rates for Internet access by end-users. The difference between average and median speeds is the way individual measurements are aggregated.
Bandwidth test software is used to determine the maximum bandwidth of a network or internet connection. It is typically undertaken by attempting to download or upload the maximum amount of data in a certain period of time, or a certain amount of data in the minimum amount of time.
The service measures the data throughput (speed) and latency (connection delay) of an Internet connection against one of over 16,000 geographically dispersed servers (as of December 2023). [7] Each test measures the data rate for the download direction, i.e. from the server to the user computer, and the upload data rate, i.e. from the user's ...
For example, this allows a central file server to establish an aggregate 2-gigabit connection using two 1-gigabit NICs teamed together. Note the data signaling rate will still be 1 Gbit/s , which can be misleading depending on methodologies used to test throughput after link aggregation is employed.
For example, if the throughput is 70 Mbit/s in a 100 Mbit/s Ethernet connection, the channel efficiency is 70%. In this example, effectively 70 Mbit of data are transmitted every second. Channel utilization is instead a term related to the use of the channel, disregarding the throughput.
Google Fiber provides an Internet connection speed of up to eight gigabits per second (8,000 Mbit/s) for download and eight gigabit per second (8,000 Mbit/s) upload. [125] Google Fiber says its original 1 Gbit/s download service allows for the download of a full movie in less than two minutes.
Gigabit wireless is the name given to wireless communication systems whose data transfer speeds reach or exceed one gigabit (one billion bits) per second. Such speeds are achieved with complex modulations of the signal, such as quadrature amplitude modulation (QAM) or signals spanning many frequencies.
The speed of light imposes a minimum propagation time on all electromagnetic signals. It is not possible to reduce the latency below = / where s is the distance and c m is the speed of light in the medium (roughly 200,000 km/s for most fiber or electrical media, depending on their velocity factor).
