What is Linux?


Linux is a free and open-source operating system. It was created by Linus Torvalds, who originally wrote it as a hobby in 1991. Since then, the project has exploded into an incredibly popular system. Linux has a number of advantages over other operating systems, including its stability, security features, efficiency and ability to execute multiple commands simultaneously. The operating system is used on a wide range of devices, including mobile phones and tablets, Chromebooks, digital video recorders, and cameras. It is also used by major cloud service providers and in data centers, and it can run on both desktop computers and server-based systems.

Unlike Windows, Linux is highly customizable. Hundreds of Linux distributions exist, each with its own unique feature set. Some of these are designed with new users in mind, while others are aimed at experienced users. Choosing the right one depends on the user’s needs and preferences. For example, many Linux distributions come with graphical programs that are more familiar to people than those that require a command line interface (CLI).

In addition to offering a large variety of desktop environments and software programs, some Linux distros are optimized for specific jobs, such as networking or data center applications. Others are designed for the latest hardware. Many of these are built from source code available on the internet, which allows users to customize the distro they are using.

To make the transition from Windows to a Linux-based operating system easier, it is recommended that people choose a distro that has documentation and an active community that can answer questions. It is also a good idea to start with a distro that will allow users to be productive as soon as possible. This way, they can get accustomed to the software quickly and will be more likely to stick with it.

Almost all Linux systems run from a kernel that is written in C programming language. It is compiled and modified by a team of developers, who are known as maintainers. The source code is released under the GNU General Public License, which stipulates that derivative work must be released under the same terms. The kernel is then assembled with other components, such as display managers, sound servers and bootloaders. These are typically based on different compilers, such as glibc aiming for speed, musl targeting embedded systems and uClibc focusing on memory usage.

Linux is very stable and has a low incidence of faults and failures, making it an ideal platform for business use. It also has a strong focus on security, which is particularly important for the financial sector. Furthermore, it is highly efficient, and it can run several processes at once without compromising performance or reducing system availability. Moreover, the operating system has many tools that help users to manage and secure their systems effectively. For these reasons, many businesses consider implementing Linux. In addition, the software is compatible with many existing hardware platforms. This makes it a highly attractive option for IT departments.
