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 ...

In telecommunications and computing, bit rate (bitrate or as a variable R) is the number of bits that are conveyed or processed per unit of time. [1]The bit rate is expressed in the unit bit per second (symbol: bit/s), often in conjunction with an SI prefix such as kilo (1 kbit/s = 1,000 bit/s), mega (1 Mbit/s = 1,000 kbit/s), giga (1 Gbit/s = 1,000 Mbit/s) or tera (1 Tbit/s = 1,000 Gbit/s).

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.

For Blu-ray discs, 1× speed is defined as 36 megabits per second (Mbit/s), which is equal to 4.5 megabytes per second (MB/s). [7] However, as the minimum required data transfer rate for Blu-ray movie discs is 54 Mbit/s, the minimum speed for a Blu-ray drive intended for commercial movie playback should be 2×. The fastest Blu-ray speed is 16×.
The bit rate for this example is 64 Gbit/s (8 × 8 × 10 9 bit/s). The formula for a data transfer rate is: Channel width (bits/transfer) × transfers/second = bits/second . Expanding the width of a channel, for example that between a CPU and a northbridge , increases data throughput without requiring an increase in the channel's operating ...
