ITPEC IP April 2019 Question 18
Which of the following explains the functions of an archiver, which is one (1) type of data management utility?
Explanation
Packs multiple files into a single file or restores them, for backup or distribution — that is an archiver.
An archiver gathers many files, often a whole folder, into one archive file, usually compressing them as well (ZIP is a common format), and extracts the original files from it again. One file is easier to back up, attach to an e-mail or download than many.
Answer (b)
Why not others:
- •(a) — creating storage areas on a disk and managing the data in them is partitioning and formatting, the work of disk management and the file system
- •(c) — file protection and copy protection are security and access-control functions
- •(d) — rearranging a fragmented file into consecutive blocks is defragmentation, done by a defragmenter
Key rule: Archiver: many files into one and back; defragmenter: one file's scattered blocks made consecutive; formatter: prepares the disk to hold files.
