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
Data compression corresponds to II because it represents information using fewer bits.
Data encryption corresponds to III because it scrambles readable message text into an encoded form.
Disk defragmentation corresponds to IV because it compacts scattered file fragments to create larger contiguous free-space regions.
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.
