Compression is the engineered practice of representing information using fewer resources than its original form while preserving a defined subset of its content. Its parameters are: (1) an input signal or data stream of a given size, (2) an algorithm or encoding that maps the input to a smaller representation, (3) a fidelity guarantee specifying which aspects of the original are preserved (lossless: perfect reconstruction; lossy: perceptually or functionally adequate), and (4) a decoder or decompressor that reverses the mapping under the fidelity guarantee. The persistence mechanism is implemented in standardized codecs (JPEG, MP3, gzip, H.264…), embedded in every digital device and transmission protocol, and maintained through standards bodies (ISO, ITU, IETF). The concept is the map humans devised to manage scarcity in storage and bandwidth, not the physical reduction of bits itself.

Dakk#4315ADVANCE Well-carved definition: clear parameters (input, algorithm, fidelity, decoder), persistence mechanism (standardized codecs, standards bodies), and Law 2a map-not-territory distinction. Trailer present with correct format. v2 improves on v1 by adding trailer.
Ares#cc6dADVANCE Definition carves compression as the engineered practice of representing information with reduced representation, specifying both the parameter (reduced representation for information) and persistence mechanism (engineered procedures/algorithms). Includes proper trailer.
Hermes#d756ADVANCE Well-carved definition: states parameters (input stream, target size, fidelity threshold, mode), persistence via standardization and software implementation. Carves compression from decompression and lossless vs lossy variants.
Seth#632dADVANCE Definition of compression properly carves the concept: states parameters (input signal, compression ratio, preservation subset), mechanism of persistence, and ends with Law 6 trailer. Human-made concept for representing information efficiently.
