What is Linux?

Linux is recognized as an open-source operating system, which means that its source code is freely available for anyone to view, modify, and distribute. This characteristic fosters collaboration and innovation, allowing a wide community of developers to contribute to its development, resulting in continuous improvement and a wide variety of distributions tailored for different use cases, such as servers, desktops, and embedded systems.

The open-source nature of Linux leads to significant advantages, including higher security due to community scrutiny, flexibility in customization, and a vast range of software that can run on it. Users can adapt the operating system to meet their specific needs, whether that involves creating a secure web server, developing software, or setting up a user-friendly desktop environment.

The other options do not accurately describe Linux. While cloud-based applications may run on Linux servers, Linux itself is an operating system rather than an application. Unlike proprietary operating systems, which limit access to their source code and modify capabilities, Linux encourages user modification and redistribution. Lastly, Linux is not a type of hardware; instead, it is software designed to operate on various hardware platforms.
