File size is a measure of how much data a computer file contains or, alternately, how much storage it consumes. Typically, file size is expressed in units of measurement based on the byte.
This is a list of interface bit rates, is a measure of information transfer rates, or digital bandwidth capacity, at which digital interfaces in a computer or network can communicate over various kinds of buses and channels.
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.
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 the history of optical storage media there have been and there are different optical disc formats with different data writing/reading speeds.. Original CD-ROM drives could read data at about 150 kB/s, 1× constant angular velocity (CAV), [1] the same speed of compact disc players without buffering.
The megabyte is a multiple of the unit byte for digital information. Its recommended unit symbol is MB.The unit prefix mega is a multiplier of 1 000 000 (10 6) in the International System of Units (SI). [1]
Lossless compression of digitized data such as video, digitized film, and audio preserves all the information, but it does not generally achieve compression ratio much better than 2:1 because of the intrinsic entropy of the data.
