What is Linux?

Linux is a open-source kernel based on the Unix operating system. After it came into existence It became one of the most widely used operating systems in the world. The Linux kernel was released under the GNU General Public License (GPL), which means that anyone can use, modify, and distribute it freely as long as they share their modifications with other members of the Linux community.

How was Linux Created?

Linux was created by Linus Torvalds, a computer science student at the University of Helsinki, in 1991. Torvalds was interested in operating systems and had been using the Unix operating system on the university’s computers. He wanted to create his own operating system that would be free and open-source and could run on his personal computer and thus Linux was created with his vision.

Who Owns Linux?

Linux is an open-source operating system that is not owned by any one individual or company. Instead, it is managed by a global community of developers who work together to improve and maintain the software. The Linux kernel, which is the core component of the operating system, is distributed under the GNU General Public License (GPL), which grants users the freedom to use, modify, and distribute the software.

The trademark of Linux is owned by Linus Torvalds, though there is a non-profit organization named as the Linux Foundation that supports the development and promotion of the Linux operating system and some other open-source software projects based on Linux. The Linux Foundation provides a neutral forum for collaboration and innovation among developers, users, and companies that use and support Linux.

Features of Linux

The key features of Linux are as follows:

• Open-source: Linux is open-source software, which means that the source code is freely available to anyone who wants to use, modify, or distribute it.
