Information about Compression (disambiguation)

<includeonly></includeonly>A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume. Compression of a gas naturally increases its temperature.

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.

A compression arch suspended-deck bridge, or through arch bridge, is a bridge made from modern materials such as steel or reinforced concrete in which a compression arch rises above the deck. Cables connect the deck to the arch.

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.

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 transmit data in an efficient form.

Image compression can be lossy or lossless.

Video compression refers to reducing the quantity of data used to represent video images, and this is almost always coupled with the goal of retaining as much of the original's quality as possible.

compression artifact (or artefact) is the result of an aggressive data compression scheme applied to an image, audio, or video that discards some data which is determined by an algorithm to be of lesser importance to the overall content but which is nonetheless discernible

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.
• The reduction of the time needed to transmit a given amount of data in a given bandwidth.
