Which statement best describes data compression?

AThe process of calculating the file size of a saved file

BThe process of encoding characters into more than one language

CThe process of encoding information to try and use fewer bits than the original data ✓ Correct

DThe process of removing necessary data from a file

Correct answer: (C) The process of encoding information to try and use fewer bits than the original data

Explanation

Data compression encodes information to use fewer bits than the original data.

It shrinks file size so data needs less storage and transfers faster.

It is not merely calculating the size of a saved file.

It does not mean encoding characters into more than one language.

It should not remove necessary data, which would corrupt the file.

Lossless compression restores data exactly, while lossy discards some detail.
