Linux is a free and open-source operating system that is based on the Unix operating system. It was first created by Linus Torvalds in 1991 as a hobby project, and has since become one of the most widely used operating systems in the world.
The Linux operating system is known for its stability, security, and flexibility. It is used in a variety of applications, from servers and supercomputers to desktop computers and mobile devices. Linux is also used in many embedded systems, such as routers, smart home devices, and automotive systems.
One of the key features of Linux is that it is open source, which means that the source code is freely available for anyone to modify and distribute. This has led to a large and active community of developers who contribute to the ongoing development of the operating system.
Linux comes in many different distributions, each with its own unique features and characteristics. Some of the most popular distributions include Ubuntu, Debian, Red Hat, and CentOS.
Today in this article I am going to tell you What is Linux Operating System, so let’s get started…
Brief Descriptions of The Content
What Is Linux Operating System
Linux is a free and open-source operating system kernel that was first released on September 17, 1991, by Linus Torvalds. It is based on the Unix operating system and is designed to be lightweight, stable, and highly customizable. Linux is widely used in web servers, supercomputers, smartphones, and embedded devices, as well as in desktop and laptop computers.
One of the key features of Linux is its open-source nature, which means that its source code is freely available and can be modified and distributed by anyone. This has led to a large community of developers who contribute to the development of Linux and its associated software.
Linux also has a reputation for being more secure than other operating systems, as it has fewer security vulnerabilities and is less susceptible to malware and viruses. Additionally, Linux has a large library of free and open-source software applications that can be easily installed and used, which makes it an attractive choice for many users.
There are many different distributions, or “distros,” of Linux available, each with its own set of features and characteristics. Some popular distros include Ubuntu, Debian, Fedora, and CentOS.
Who Is the Owner of Linux
Linux is not owned by any individual or company. Instead, it is a free and open-source operating system kernel that was originally created by Linus Torvalds, a Finnish software engineer, in 1991. Torvalds created Linux as a personal project while he was a student at the University of Helsinki, and he released it under the GNU General Public License, which allows anyone to use, modify, and distribute the software as long as they adhere to certain conditions.
Since its release, Linux has been developed and maintained by a community of volunteers, developers, and companies who contribute to its development and support its users. The Linux kernel is managed by a group of developers known as the Linux kernel community, who oversee its development and release new versions on a regular basis. While no one owns Linux, many companies, including Red Hat, IBM, and Intel, have contributed to its development and provide support and services for Linux users.
History of Linux
Linux has a rich and interesting history, which spans over three decades. Here is a brief overview of its major milestones:
- In 1991, Linus Torvalds, a Finnish computer science student, started developing the Linux kernel as a personal project. The kernel was initially based on the MINIX operating system, which was a Unix-like system designed for educational purposes.

Is Linux Operating System completely Malware free
While Linux is generally considered to be less susceptible to malware and viruses than other operating systems, it is not completely immune to these threats. While the open-source nature of Linux does provide some benefits in terms of security, it also means that the source code is available to potential attackers who can study it for vulnerabilities.
Additionally, while Linux does have built-in security features such as permissions-based file system access and built-in firewalls, these features are not foolproof and can be bypassed by determined attackers.
That being said, Linux is generally considered to be a more secure operating system than many other alternatives, such as Windows. This is due in part to its lower market share, which makes it less of a target for attackers, and in part to its design, which places a greater emphasis on security and stability.
In summary, while Linux is not completely malware-free, it is generally considered to be a more secure operating system than many other alternatives. However, it is still important for users to take precautions such as keeping their software up-to-date, using strong passwords, and using antivirus and other security software to help protect against potential threats.
