ITPEC FE Morning October 2023 Question 19

Combining several files into one, and restoring them, for backup and distribution — that is what an archiver does.

An archiver (for example tar or zip) packs a set of files, often with their folder structure, into a single archive file that is easy to store or send, and extracts the original files again later. Many archivers also compress the data.

Answer (a)

Why not others:

• •(b) — describes formatting a disk, which sets up the management area (directory, allocation table) and the data area
• •(c) — describes file protection and copy protection, which are security functions
• •(d) — describes defragmentation, which moves the parts of fragmented files into contiguous areas

Key rule: Match each utility to its job: archiver bundles files, formatter prepares a disk, defragmenter reorders blocks, protection tools control access and copying.
