In this article, we’ll explore Linux’s history, its role in the tech ecosystem, and why it remains a favorite for developers, enterprises, and hobbyists alike.
The Origins of Linux
Linux was created in 1991 by Linus Torvalds, a Finnish computer science student who sought to develop a free operating system kernel. Torvalds initially built Linux as a personal project, inspired by MINIX, a Unix-like operating system. What set Linux apart was its open-source nature, allowing anyone to access, modify, and distribute the source code.
The open-source ethos resonated with a global community of developers, who quickly rallied around Linux. Together, they enhanced its capabilities, laying the foundation for a vibrant ecosystem that continues to flourish today.
Key Features of Linux
Linux’s enduring popularity stems from its robust features, including:
