The 24 pages that link to Data compression, each with the reason it gives.

• Information theoryRelated: Information-theoretic limits distinguish achievable lossless and lossy compression.

• Claude ShannonRelated: Shannon’s source-coding results establish fundamental limits on lossless compression.

• Error-correcting codeCompared with: Compression removes redundancy, while error correction adds it to improve reliability.

• Shannon entropyNarrower topic: Entropy estimates the irreducible coding cost when a source distribution is known.

• BitRelated: Compression reduces the number of bits needed to store or transmit information.

• Audio codecNarrower topic: Audio codecs are specialized compression systems built around the structure and perception of sound.

• File formatRelated: A format may specify compression to reduce file size, sometimes with information loss.

• Digital mediaRelated: Compression reduces storage and transmission costs for large media files.

• Sufficient statisticRelated: A sufficient statistic compresses a sample without losing information about the specified parameter.

• Coding theoryCompared with: Compression removes redundancy, while error-correcting codes deliberately add it.

• A Mathematical Theory of CommunicationRelated: The source coding results explain theoretical limits on lossless compression.

• Cartographic generalizationCompared with: Compression reduces storage or transmission size; generalization changes geographic representation for map use.

• DigitizationRelated: Compressed files reduce the storage and transmission costs of digitized material.

• Dial-up Internet accessRelated: Compression could raise effective throughput without increasing the line's raw signaling rate.

• Algorithmic information theoryRelated: Kolmogorov complexity is an ideal limit on lossless compression, though it is uncomputable.

• Coarse-grainingCompared with: Both reduce information, but coarse-graining targets physical description rather than compact encoding.

• RedundancyCompared with: Compression removes predictable structure that redundancy makes available.

• Digital dataRelated: Compression makes digital files smaller to store or transmit.

• Shannon's source coding theoremRelated: The theorem explains why probability-aware encoders can outperform fixed-length representations.

• Filename extensionRelated: Compressed files commonly use extensions that suggest their archive or compression format.

• Multimedia (computing)Related: Compression reduces the storage and bandwidth demands of large media files.

• Computer data storageRelated: Compression reduces the capacity needed to store data, often trading processing time.

• WinRARNarrower topic: WinRAR reduces archive size through compression algorithms.

• Information and communication theoryRelated: Source coding formalizes the limits and tradeoffs involved in compression.
