Show answer & explanation

Correct answer: C

Concept

A technical term should be matched to the operation it performs, not merely to another term from the same computing domain.

Compression reduces the number of bits, encryption transforms readable data for confidentiality, defragmentation reorganizes scattered disk blocks, and formatting prepares storage for use.

Application

  1. Data compression corresponds to II because it represents information using fewer bits.

  2. Data encryption corresponds to III because it scrambles readable message text into an encoded form.

  3. Disk defragmentation corresponds to IV because it compacts scattered file fragments to create larger contiguous free-space regions.

  4. Disk formatting corresponds to I because it prepares a storage device with the structures needed for initial use.

Cross-check

Computer term

Matched description

Data compression

II — fewer-bit representation

Data encryption

III — scrambled message text

Disk defragmentation

IV — larger contiguous free-space regions

Disk formatting

I — storage prepared for initial use

Therefore, the matching sequence is A–II, B–III, C–IV, D–I.
