Interviewer: A 5GB file shrinks to 1.2GB after compression No Data lost, no quality degraded. If nothing is lost, what exactly is compression eliminating?🤔

@suni_code Compression finds repeated patterns in the file. It replaces those repeats with short codes that stand for the same thing. When you open the file again the short codes turn back into the full original data. No information disappears. The file just uses space in a better way.

@ConsciousRide nicely explained 🙌🏻
