Compression of data meaning

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 process of encoding, restructuring or otherwise modifying data in order to reduce its size. Fundamentally, it involves re-encoding information using fewer bits than the original representation.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.Data compression is the process of reducing the size of digital data while preserving the essential information contained in them.Compressing a data set is a process that reduces the number of bytes that are required to represent each observation in a file. You might choose to enable compression to reduce the storage requirements for the file and to lessen the number of I/O operations that are needed to read from or write to the data during processing.
