Data compression definition and explanation

Data compression, also called compaction, the process of reducing the amount of data needed for the storage or transmission of a given piece of information, typically by the use of encoding techniques.

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.Data compression is the process of modifying, encoding or converting the bits structure of data in such a way that it consumes less space on disk.In computer science and information theory, data compression, source coding, or bit-rate reduction involves encoding information using fewer bits than the original representation. Compression can be either lossy or lossless. Lossless compression reduces bits by identifying and eliminating statistical redundancy.In information theory, data compression, source coding, or bit-rate reduction is the process of encoding information using fewer bits than the original representation.
