Data compression is the process of encoding computer data so that it takes less storage space than if the data was not compressed.

Data compression is a fundamental computer science issue.

Compressed data is data that has been passed through a data compression software system.

Uncompressed data is data that has not been passed through a data compression software system.

Fundamental compression methods

Data compression topics:

A very simple data compresson algorithm would be to replace all instances of the string 'this_is_a_long_string' with '514a' in a text file.

Closely allied with data compression is field of [information coding]? and cryptography.

Common Data compression algorithms:

The idea of data compression is deeply connected with statistic inference and particularly with the maximum likelihood principle.
