解説
問 89
- ア
正解 Only statement (1) is correct, so “ア”, which lists only (1), is the right answer. (1) The Apache HTTP Server is a representative OSS (Open Source Software) that is widely used around the world as a web server; its source code is public, and anyone can freely use, modify, and redistribute it. Therefore (1) is correct, and “ア”, which contains only this item, lists exactly the correct ones with nothing missing or extra.
Incorrectイ
(1) is correct, but (2) is wrong. Internet Explorer in (2) is a proprietary web browser developed by Microsoft; its source code is not public, and it is not OSS. “イ”, which includes the incorrect (2), is not appropriate.
Incorrectウ
Both (2) and (3) are wrong. Internet Explorer in (2) is not OSS. As for (3), OSS business integrated suites (office software) that include word processing, spreadsheets, and presentations — such as LibreOffice and Apache OpenOffice — are in fact developed and provided, so “has not been developed” is incorrect. In addition, it does not contain the correct (1).
Incorrectエ
(3) is wrong. OSS office integrated suites (such as LibreOffice and Apache OpenOffice) have in fact been developed, so “has not been developed” does not hold. Furthermore, it does not contain the correct (1), so it fails to list the correct items.
ここがポイント
- OSS (Open Source Software) is software whose source code is public and that anyone can freely use, modify, and redistribute. Representative examples include the Apache HTTP Server, Linux, Firefox, and LibreOffice.
- Grasp the distinction that commercial, proprietary products like Internet Explorer keep their source code closed and are not OSS.
