  • Compression member, a class of structural elements, of which a column is the most common specific example
  • Compressibility, a measure of volume change resulting from pressure, the reciprocal of the bulk modulus
• Gas compression, raising the pressure and reducing the volume of gases
  • Compression ratio, a figure of merit for an internal-combustion engine
• Compression (geology), a system of forces that tend to decrease the volume of or shorten rocks

[edit] Information science

• Data compression, the process of encoding information using fewer bits
  • Audio compression (data), the compression of digital audio streams and files
  • Bandwidth compression, a reduction in either the time to transmit or in the amount of bandwidth required to transmit
  • Compression artifact, noticeable defects in audio or video that has been compressed
  • Image compression, the application of data compression on digital images
  • Video compression, the compression of digital video streams and files

• Compression (functional analysis), the compression of a linear operator "T" on a Hilbert space to a subspace "K" is the operator
• Compression bandage, a bandage that uses compression to reduce the flow of blood
• Compression (phonetics), running syllables together in informal speech
• Compression (zoology) when an animal, or part of an animal, is shorter or narrower compared with other animals in the same group; e.g. the body of a lizard may be "compressed" (flattened) so it can better fit into crevices under rocks
• Gain compression, in electronic amplifiers, a reduction in differential or slope gain resulting from device non-linearity
