Linux is a operating system Unix-like, based on the Linux kernel, created by Linus Torvalds in 1991. As software open source, it provides the freedom for users to review, modify and distribute the source code. A Linux system mainly consists of core, which manages the computer’s hardware resources, and a set of applications and tools that allow users to interact with the system.
The operation of Linux is based on the management of process, from the memory and inputs/outputs. THE operating system allocates the necessary resources to current applications and ensures that the different processes do not disrupt each other. Additionally, Linux is known for its stability, its severability and its subcontracting increased, making it a preferred choice for servers and the environments of development.
Linux is a open source operating system which has revolutionized the world of computing since its creation in 1991 by Linus Torvalds. Thanks to its structure based on a core, Linux has become the basis of many distributions, thus offering great flexibility and a wide range of applications. This article will provide you with an in-depth understanding of what Linux is, how it works, and its advantages over other operating systems.
What is Linux?
Linux, or more precisely GNU/Linux, is a Unix-like operating system. It is made up of a kernel – the heart of the system – and a set of programs and tools open source. This open model allows users to modify and customize the system according to their needs. Linux distributions, such as Ubuntu, Fedora or Red Hat, are complete packages built around this kernel, each offering unique specifications in terms of interface and default applications.
How does Linux work?
The way Linux works is based on a computer resource management model that efficiently allocates computer resources, such as processor and the memory, to running processes. The Linux kernel handles essential tasks such as file management, peripherals, and communications between programs.
The Linux kernel
The kernel is the centerpiece of any Linux system. It acts as an intermediary between hardware and software, managing the system’s access to hardware resources. The kernel design promotes stability and security, which is crucial when used for mission-critical applications on servers.

Command line and user interfaces
Although many Linux distributions offer user-friendly desktop environments, the command line remains a powerful tool for system administration and management. It allows you to control almost every aspect of Linux using text commands. For those who want to better understand how to use the command line, a detailed guide is available here: the command line in Linux.
The advantages of Linux
Linux has gained popularity, particularly for its use in servers. Its ability to operate robustly and securely, while being customizable, makes it an ideal choice for businesses. Additionally, usage costs are often lower than commercial operating systems because there are no associated licensing fees.

Linux distributions
There are many Linux distributions, each designed to meet different needs. For example, some distributions like Ubuntu focus on user experience and accessibility, while others, like Debian, offer increased stability. The variety of distributions allows users to choose a system that best suits their specific requirements.
