Which is Linux?

Correct option is A

Linux is an open-source operating system. It is a Unix-like operating system that is freely available to the public, and its source code can be modified, distributed, and used by anyone. Linux is known for its robustness, security, and versatility, and it is used on various platforms, from personal computers to servers and embedded systems.
Important Key Points:
1. Open-Source: Linux's source code is publicly available under an open-source license, allowing anyone to inspect, modify, and distribute it.
2. Operating System: Linux is an operating system, not an application software. It manages hardware resources and provides services for applications to run.
3. Variants: There are several distributions (distros) of Linux, such as Ubuntu, Fedora, and Debian, each offering different features and packages for various user needs.
Knowledge Booster:
· Option (b): Open-source application software refers to software programs (like web browsers or office suites) that are open source, not the operating system itself.
· Option (c): Windows-based application software refers to software that runs on the Windows operating system. Linux is not related to Windows.
· Option (d): Proprietary Operating System refers to operating systems that are not open-source, such as Windows or macOS. Linux, being open-source, is the opposite of a proprietary OS.
