解説
問 69
Incorrectア
A pattern file is a definition file that collects the characteristic (pattern) information used by antivirus software to detect known malware. It is updated to keep virus detection accurate, and it is not a file meant to fix defects in the software itself.
Incorrectイ
A backup file is a spare copy that duplicates and stores data or systems in preparation for data loss or failure. Its purpose is to keep a copy for recovery, and it is not something provided to fix software defects.
Incorrectウ
A batch file is a file that describes instructions for automatically running multiple commands or processes together. Its purpose is to execute processing in a batch, and it is not a correction file distributed to fix defects.
- エ
正解 A “patch” refers to a small correction program or data that is distributed afterward in order to fix a software defect (bug) or a security flaw. When it is provided as a file, it is called a “patch file”, and by applying it users can partially update or fix existing software. Therefore, the option matching the question's “file provided to fix a defect” is エ, the patch file.
ここがポイント
- Patch = a correction file distributed to fix software defects or security flaws after the fact; applying it partially updates existing software.
- Distinguishing confusable terms: pattern file (virus definitions), backup file (data copy), and batch file (running commands in a batch) each serve different purposes.
