WebOct 16, 2024 · The term compression ratio refers to a fraction, percentage or ratio that expresses the difference between the size of a file before it was compressed and after the compression process is complete. This ratio depends on multiple different factors – mostly, the state of the initial file and the algorithm used to compress the file. WebMar 2, 2024 · Data compression is the act or process of reducing the size of a computer file. Through an algorithm or a set of rules for carrying out an operation, computers can determine ways to shorten long strings of data and later reassemble them in a recognizable form upon retrieval.
