How does Linux work?
Linux is a type of operating system (OS) that is based on the Unix operating system. It is open-source software, which means that anyone can access and modify the source code. This makes Linux a popular choice for developers, businesses, and individuals who want a powerful, customizable, and secure operating system.
In this article, we will take a closer look at how Linux works and what makes it different from other operating systems. We will also discuss some of the most popular Linux distributions, or “distros,” and provide examples of how Linux is used in the real world.
What is an Operating System?
An operating system (OS) is a collection of software that manages the resources of a computer and provides an interface for users and applications to interact with the hardware. The OS is responsible for tasks such as managing memory, processing input and output, and managing the file system.
There are several types of operating systems, including Windows, MacOS, and Linux. Each of these operating systems has its own set of features and capabilities, and they are used in different ways.
Linux is a type of Unix-like operating system, which means that it is based on the same principles and design as the Unix operating system. Unix was developed in the 1970s by a group of researchers at Bell Labs. It was designed to be a powerful, multi-user operating system that could be used for a wide range of applications.
Linux is similar to Unix in many ways, but it is also different in some key ways. One of the main differences is that Linux is open-source software, which means that anyone can access and modify the source code. This makes Linux a popular choice for developers and businesses that want a powerful, customizable, and secure operating system.
The Linux kernel is the core of the operating system. It is responsible for managing the resources of the computer, such as memory and processing power. The kernel also provides an interface for users and applications to interact with the hardware.
The Linux kernel is written in C and assembly language and is designed to be portable, which means that it can be used on a wide range of hardware platforms. This makes Linux a popular choice for servers, desktops, and embedded systems.
One of the most powerful features of Linux is its package management system. A package is a collection of software and related files that can be easily installed, updated, and removed from the operating system.
There are several popular package management systems for Linux, including apt, yum, and pacman. Each of these package management systems has its own set of features and capabilities, and they are used in different ways.
There are several popular Linux distributions, or “distros,” that are used in the real world. Each of these distros has its own set of features and capabilities, and they are used in different ways.
Here are a few examples of popular Linux distros:

This makes Linux a popular choice for developers, businesses, and individuals who want a powerful, customizable, and secure operating system.
The Linux kernel is the core of the operating system, and it is responsible for managing the resources of the computer. Linux also includes a wide range of tools and utilities that make it easy to manage and customize the operating system.
One of the most powerful features of Linux is its package management system, which makes it easy for users to install and update software on their Linux systems. This is because package management systems automatically handle dependencies, which are other software packages that are required for a specific piece of software to work properly.
What is Linux?
Linux® is an open source operating system (OS). An operating system is the software that directly manages a system’s hardware and resources, like CPU, memory, and storage. The OS sits between applications and hardware and makes the connections between all of your software and the physical resources that do the work.
What’s a command line?
The command line is your direct access to a computer. It’s where you ask software to perform hardware actions that point-and-click graphical user interfaces (GUIs) simply can’t ask.
Command lines are available on many operating systems—proprietary or open source. But it’s usually associated with Linux, because both command lines and open source software, together, give users unrestricted access to their computer.
Our latest release of Red Hat® Enterprise Linux comes with even more built-in command line capabilities than ever before and includes consoles that bundle those capabilities in easy-to-use modules that exist off of the command line.
How does Linux work?
Think about an OS like a car engine. An engine can run on its own, but it becomes a functional car when it’s connected with a transmission, axles, and wheels. Without the engine running properly, the rest of the car won’t work.
Linux was designed to be similar to UNIX, but has evolved to run on a wide variety of hardware from phones to supercomputers. Every Linux-based OS involves the Linux kernel—which manages hardware resources—and a set of software packages that make up the rest of the operating system. Organizations can also choose to run their Linux OS on a Linux server.
The OS includes some common core components, like the GNU tools, among others. These tools give the user a way to manage the resources provided by the kernel, install additional software, configure performance and security settings, and more. All of these tools bundled together make up the functional operating system. Because Linux is an open source OS, combinations of software can vary between Linux distributions.
