When talking about circuit bit rates, people will interchangeably use the terms throughput, bandwidth and speed, and refer to a circuit as being a '64 k' circuit, or a '2 meg' circuit — meaning 64 kbit/s or 2 Mbit/s (see also the List of connection bandwidths). However, a '64 k' circuit will not transmit a '64 k' file in one second.
This is a sortable list of broadband internet connection speed by country, ranked by Speedtest.net data for March 2024, [1] and with M-Lab data for June 2023 [2] Country/Territory Median
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 computer to the server. The tests are performed within the user's web browser or within mobile apps. As of 17 February 2024, over 52.3 billion Internet speed tests have been completed. [8]
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).

The ISQ symbols for the bit and byte are bit and B, respectively.In the context of data-rate units, one byte consists of 8 bits, and is synonymous with the unit octet.The abbreviation bps is often used to mean bit/s, so that when a 1 Mbps connection is advertised, it usually means that the maximum achievable bandwidth is 1 Mbit/s (one million bits per second), which is 0.125 MB/s (megabyte per ...
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.
By bonding the connections from multiple Ethernet ports via IEEE 802.3ad link aggregation or similar, manufacturers were able to achieve speeds close to 2 Gbit/s by using two ports that support gigabit speeds. This would require the wireless access point to be connected to the rest of the network with 2 Ethernet cables and require both the ...
