Show answer & explanation
Correct answer: A
Concept
An operating system is system software that manages computer hardware and provides a platform and services for application programs.
In an odd-one-out question, every choice must be compared using one common classification criterion.
Application
Item | Classification |
|---|---|
Windows | Windows names an operating-system family developed by Microsoft. |
Linux | Linux names an open-source operating-system family used through many distributions. |
macOS | macOS names the operating system developed by Apple for Mac computers. |
Google names a technology company and brand of internet products; it does not itself name an operating system, although the company develops operating systems such as Android and ChromeOS. |
Cross-check
Using the operating-system classification consistently, Windows, Linux, and macOS fall in the same category, while Google does not. Therefore, Google is the different member.
