Data compression
A useful mental model for the technology shaping daily life.
The useful idea
- The useful idea
In information theory, data compression, source coding, or bit-rate reduction is the process of encoding information using fewer bits than the original representation.
- How it works
Any particular compression is either lossy or lossless.
- Why it matters
Lossless compression reduces bits by identifying and eliminating statistical redundancy.
Why this matters
Use Data compression as a lens when judging what a digital tool can — and cannot — do.
