	Compression may refer to: In physical science: Physical compression Physical compression Physical compression is the result of the subjection of a material to compressive stress, resulting in reduction of volume. The opposite of compression is tension .... , the result of the subjection of a material to compressive stress Compression member Compression member A compression member is a general class of structural elements of which a column is the most common specific example.... , a class of structural elements, of which a column is the most common specific example Compressibility, the reciprocal of the bulk modulus Bulk modulus The bulk modulus of a substance measures the substance's resistance to uniform compression. It is defined as the pressure increase needed to cause a given relative decrease in volume.... (typically for solids) Gas compression, raising the pressure and reducing the volume of gases Compression ratio Compression ratio The compression ratio of an internal-combustion engine or external combustion engine is a value that represents the ratio of the volume of its combustion chamber; from its largest capacity to its smallest capacity.... , a number that predicts the performance of any internal-combustion engine Compressibility Compressibility In thermodynamics and fluid mechanics, compressibility is a Measure of the relative volume change of a fluid or solid as a response to a pressure change.... , a measure of volume change resulting from pressure (typically for fluids) Compression (geology) Compression (geology) In geology the term compression refers to the system of forces that tend to decrease the volume of or shorten rocks. Compressive strength refers to the maximum compressive stress that can be applied to a material before failure occurs.... , a system of forces that tend to decrease the volume of or shorten rocks In information science: Data compression Data compression In computer science and information theory, data compression or source coding is the process of encoding information using fewer bits than an code representation would use through use of specific encoding schemes.... , the process of encoding information using fewer bits Image compression Image compression Image compression is the application of Data compression on digital images. In effect, the objective is to reduce redundancy of the image data in order to be able to store or data transmission data in an efficient form.... Audio data compression Video compression Video compression Video compression refers to reducing the quantity of data used to represent digital video images, and is a straightforward combination of and motion compensation.... Compression artifact Compression artifact A compression artifact is the result of an aggressive data compression scheme applied to an , Sound recording, or video that discards some data that may be too complex to store in the available data-rate, or may have been incorrectly determined by an algorithm to be of little subjective importance, but is in fact objectionable to the view... , noticeable defects in audio or video that has been compressed Bandwidth compression Bandwidth compression In telecommunication, the term bandwidth compression has the following meanings:The reduction of the Bandwidth needed to transmit a given amount of data in a given time.... , in telecommunications Gain compression Gain compression Gain compression* in an electronic amplifier circuit is a reduction in 'differential' or 'slope' gain caused by nonlinearity of the transfer function of the amplifying device.... , in electronic amplifiers, a result of device non-linearity Audio level compression Audio level compression Dynamic range compression, also called DRC or simply compression, is a process that reduces the dynamic range of an audio signal. Compression is used during sound recording, live sound reinforcement, and broadcasting to control the level of audio.... , usually artificially introduced gain compression to improve the perceived quality of audio In other sciences and technologies: Engine compression, in automotive use, usually expressed as a Compression ratio Compression ratio The compression ratio of an internal-combustion engine or external combustion engine is a value that represents the ratio of the volume of its combustion chamber; from its largest capacity to its smallest capacity....
