Compression vs. Decompression — What's the Difference?

The act or process of compressing.

The act or process of decompressing.

The state of being compressed.

A surgical procedure used to relieve pressure on an organ or part, such as the abdomen, cranium, or spinal cord.

The process by which the working substance in a heat engine, such as the vapor mixture in the cylinder of an internal-combustion engine, is compressed.

The process of decompressing.

The engine cycle during which this process occurs.

The restoration to atmospheric pressure of a person who has spent time under higher pressure (such as a diver).

(Computers) The process by which data is compressed into a form that minimizes the space required to store or transmit it.

A mode of operation of some internal combustion engines which reduces the engine's compression ratio, making it easier to start but significantly increasing fuel consumption.

An increase in density; the act of compressing, or the state of being compressed; compaction.

(medicine) The relief of pressure on a body part by surgery.

(automotive) The cycle of an internal combustion engine during which the fuel and air mixture is compressed.

The process of experiencing decompression; the act or process of relieving or reducing pressure.

(computing) The process by which data is compressed.

The reduction of atmospheric pressure experienced by divers rising from deep water to the surface, thus reducing the concentration of dissolved atmospheric gases in the blood; - especially applied to a gradual reduction of such pressure.

(music) The electronic process by which any sound's gain is automatically controlled.

The process, analogous to sense 2, undergone by divers in a decompression chamber, in which an artificially high atmospheric pressure is gradually lowered to normal pressure.

(astronomy) The deviation of a heavenly body from a spherical form.

A return to a normal, more relaxed state after a period of intense stress, psychological pressure, or urgent activity; - of people.

The act of compressing, or state of being compressed.

The process of converting digitally encoded data from a more compact (compressed) form to its original, larger size.

Reduction of the space required for storage (of binary data) by an algorithm which converts the data to a smaller number of bits while preserving the information content. The act of compressing {3}.

Restoring compressed information to its normal form for use or display

An increase in the density of something

Relieving pressure

The process or result of becoming smaller or pressed together;

Encoding information while reducing the bandwidth or bits required

Applying pressure
