IPA IP 2021 Question 83
A question IPA Japan published in 令和3年度 ITパスポート試験 公開問題 問83, translated into English. ITPEC is based on the same exams.
Which of the following is the term for combining multiple files into one (1) for the purpose of saving and storing many files?
Explanation
Archive — combining many files into a single file so that they can be saved, stored or handed on together.
An archive is one file that holds many files, often with their folder structure, and an archiver is the utility that makes it and restores the files from it. ZIP, tar and LZH are common formats. Most archivers also compress the files, which saves space, but what the term names is the bundling of multiple files into one, for long-term storage, backup or distribution.
Answer (a)
Why not others:
- •(b) Relational database — data organised in tables of rows and columns that are related through key values, not a bundle of files
- •(c) Striping — spreading data across several disks in blocks (RAID 0) to speed up reading and writing
- •(d) Swapping — moving a program's memory area out of main memory to auxiliary storage, and back, to free main memory
Key rule: Bundling several files into one for storage or distribution is archiving; striping splits one set of data across disks, the opposite direction.
