data compression ratio

IBM advertising suggested an expected typical 3:1 data compression ratio.

Therefore, subsequent revisions of an article can be concatenated and then compressed, achieving very high data compression ratios of up to 100x.

Data compression ratio is defined as the ratio between the compressed size and the uncompressed size:

The data compression ratio is analogous to the physical compression ratio used to measure physical compression of substances.

The quantity is called the relative redundancy and gives the maximum possible data compression ratio, when expressed as the percentage by which a file size can be decreased.

Data compression ratio, also known as compression power, is a computer-science term used to quantify the reduction in data-representation size produced by a data compression algorithm.

Using data compression ratios in excess of 5:1, they have squeezed the text on the three 8 megabit ROM chips plus 32k of RAM.

Algorithmic and code efficiency (data need only be encoded once and branch table code is usually compact), and the potential to attain high data compression ratios.

The data compression ratio can serve as an measure of the complexity of a data set or signal, in particular it is used to approximate the algorithmic complexity.

The dialogue during the tour ranged from data compression ratios to xenon bulbs, from encryption software to the Pluto hard drive array, which stored the film on a bank of 20 hard disks.

A modern example of information leakage is the leakage of secret information via data compression, by using variations in data compression ratio to reveal correlations between known (or deliberately injected) plaintext and secret data combined is a single compressed stream.
