This article will help you understand the real-world applications of Linux and why it’s such a popular platform. We take a deep dive into who uses Linux, what Linux is used for, and what companies use it. As the most popular operating system in the world, it comes as no surprise that one hundred percent of supercomputers use Linux .

What Is Linux?

Linux is an operating system (OS). An operating system is software that links computer hardware and the user. It’s often used in devices like smartphones, mainframes, embedded systems, computers, and tablets. An OS is used to manage hardware systems, run applications, store files, and provide an interface for users. Other common operating systems are Windows, IOS, and MacOs.

Linux’s features include a bootloader that helps to load the operating system. A kernel manages the CPU and memory. The Init system manages the bootloader, Daemon is a background processor, and the graphical server displays the visuals on your server. Linux has a desktop environment that provides user-friendly elements like desktop icons, widgets and toolbars.

What Is Linux Used For?

Linux is used in network operations, databases, desktops, mobile devices, and scientific computing. It is known as one of the most secure operating systems to use. We dive a little deeper into popular Linux uses below.


The operating system has thousands of games available to buy or download. Since it doesn’t need a high-end build for great performance, using Linux helps developers save money in game development. Users also prefer Linux because it’s customizable. The operating system allows users to change the setups as they please.


Due to Linux’s easy customization feature, the operating system is excellent for telecommunications. Operators rely on the OS to increase access and distribution of transmissions by users. Licensing terms, lower costs, security, and high performance are not the only advantages of Linux. It is also extremely reliable and popular because of the quality of its source code and testing resources.


Each user is protected by other users and they would need their own password and user ID for access. The operating system is easily customizable and modifiable and you need explicit permission to access the system. There are also Linux distributions that shield the users from hacking, such as Ubuntu and Redhat. Viruses infecting Linux systems can only affect one user account, making it easier to identify and remove.

Embedded Systems

Linux is popularly used in computers and servers because it is affordable. Other than Linux’s security and the fact that it’s reliable, most developers prefer it because of its scalability. There will always be increases in demand for everything from smart TVs and tablets to car navigation systems and satellite receivers.

Software Development

Linux is versatile and fast. It features multiple open source software development tools that make the process of development easier. It features compilers, interpreters, and code editors for multiple programming languages.
