Data compression definition computer

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, 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 shrinks big files into much smaller ones. It does this by getting rid of unnecessary data while retaining the information in the file. Data compression can be expressed as a decrease in the number of bits required to illustrate data.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 using encoding, restructuring, and other modifications to reduce the size of digital data files without changing their fundamental properties. By reducing the size of files, data compression minimizes the network bandwidth required to share them and the capacity needed to store them, lowering costs.
