Which operating system is known for being open source?

Windows
Ubuntu
Linux
iOS

The correct answer is: Linux

The choice of Linux as the correct answer stems from its foundational characteristic as an open-source operating system. Open source means that the source code is publicly accessible, allowing anyone to view, modify, and distribute it. This fosters a collaborative environment among developers and users, leading to rapid improvements, security enhancements, and a diverse range of distributions tailored to different needs. Linux, created by Linus Torvalds, is a prime example of open-source software that supports a broad spectrum of applications and is used across servers, desktops, and embedded systems worldwide. Its open-source nature has led to extensive community contributions, which enhance its flexibility and security compared to proprietary systems. While Ubuntu is indeed an open-source operating system based on Linux, it is a specific distribution of the Linux kernel, emphasizing that Linux itself encompasses a wider range of distributions that maintain the open-source approach. Windows and iOS are proprietary operating systems, meaning their source codes are not available for public modification or distribution, which distinguishes them from open-source projects like Linux.
