Explanation

Data compression encodes information using fewer bits than the original representation.

Data encryption scrambles the text of a message so only authorised readers can decode it.

Disk defragmentation gathers scattered pieces to create larger regions of free space through compaction.

Disk formatting prepares a storage device for its initial use.

Each term names a distinct operation on data or on the disk that holds it.

Compression shrinks size while encryption hides meaning, two separate goals.
