Linux Applications Practical Real-World

Linux is the operating system that runs on millions of servers and desktop computers across the world. But are there any more programs that can be run on this open-source operating system?

If you use Linux on your desktop, you’ve probably pondered at some point whether or not the operating system you’re playing about with actually has any applications in the real world. Linux, fortunately, has a large number of programs that are used in the real world today. Here are a few examples of them:

1. Supercomputers

Linux also finds practical use in the realm of supercomputers. Because Linux is so widespread on supercomputers, Top500 reports that every single one of today’s supercomputer deployments uses some flavor of the Linux operating system.

It’s possible that the reasons why it’s used in super computing are similar to the reasons why it’s used in other server applications. Linux was an inexpensive operating system that was able to operate on basic x86 hardware.

In addition to that, scientists have prior experience with Unix. The researchers wouldn’t have to change their code if they used clusters of inexpensive personal computers (PCs) to execute complicated computations.

As was the case with web servers, the capacity of Linux supercomputers has increased as the operating system has been ported to other computer architectures, including as IBM’s POWER. Because of this, Linux has been able to supplant proprietary Unix systems in certain research applications, just as it has done in commercial data centers.


Supercomputers such as IBM’s Summit have been used, amongst other things, in the process of producing COVID-19 vaccinations and are currently assisting in the tracking down of variations. If you’ve already had the vaccination, it indicates that Linux has the potential to save your life.

2. Repurposing Old Computers

Even back then, a Digital PDP-7 was regarded as being insufficient for running the original version of Unix that was developed at Bell Labs. In spite of the widespread adoption of Linux distributions in place of classic Unix, the age-old practice of reusing obsolete computer hardware has not died out.

When official support from Apple or Microsoft is discontinued, and you are unable to purchase an update, or when newer versions of the operating system do not support your hardware, Linux distributions are an excellent option for continuing to utilize older machines.

When used for this purpose, minimalistic distributions perform quite well. Chrome OS Flex is a specialized variant of Google’s Chrome OS that may be installed in lieu of a computer’s native operating system and is being made available by Google.

Do not get rid of an outdated computer if you still have need for it. Instead, you may try installing a Linux distribution on it. It is possible that you may use it as a secondary computer or offer it to someone who is in need of a personal computer. In this way, you’ll also be contributing to the prevention of e-waste.

3. Backup and Recovery

Your computer is wonderful to useā€”that is, unless there is a problem. Additionally, Linux is available to assist you in times of need in the event that you find yourself in a bind.

You can try to fix your system by using the installation disc for your operating system; however, there are Linux distributions such as SystemRescue that can cure many common booting difficulties. These problems range from a broken partition table to a forgotten administrator password.

There is also the option of copying any crucial files to an external device in the event that your hard disk or SSD begins to fail. It is not necessary to be familiar with Linux in order to utilize these tools.

SystemRescue even allows you to reset your Windows password if you forget it. You never know when you’re going to require a bootable Linux distribution, which is one of the reasons why you should think about keeping one on a spare USB stick at all times.

4. Web Servers

The most common application of Linux in the real world is on servers, particularly web servers. Linux has a significant lead in the market for web servers for a number of different reasons.

Web Servers

One of the reasons for this is the fact that installing Linux does not cost too much. During the “dot-com” period of the 1990s, a large number of new businesses found Linux for this very reason. Unix-based server operating systems were already quite popular, despite their prohibitive cost and requirement of specialized hardware.

Linux was readily available for free download, and it was compatible with x86 CPUs and the open-source Apache HTTP server. This opened the door for new businesses to acquire large quantities of low-cost personal computers and employ them as servers.

These days, the vast majority of data centers and cloud service providers use specialized rack-mounted servers, which are backed by contracts purchased from businesses like as Canonical and Red Hat. Even with a contract, the license costs of open-source software are substantially lower than those of proprietary operating systems like Windows, which is one of the reasons why data centers continue to find Linux more appealing than Windows.

Even though Apache is being challenged by Nginx, Linux-based servers still outweigh Microsoft Windows servers by a considerable margin. As of May 2022, W3Techs reports that Linux servers have a market share of 37.7 percent, compared to just 20.2 percent for Windows servers.

5. Single-Board Computers

Linux may be used to power supercomputers, but it is also an excellent operating system for less complex equipment. The Raspberry Pi is the most well-known example of a single-board computer that runs Linux.

Single-Board Computers

Because it is inexpensive enough for children to purchase and experiment with, the Raspberry Pi has becoming more popular as an educational tool for teaching computer science to youngsters. It is not necessary for parents to be concerned about their children breaking something on the family computer. Linux was selected because of the availability of an ARM version, in addition to the fact that it is an open-source operating system.

It is also common for use in modest embedded computer projects, and the Raspberry Pi may be put to practically any practical purpose that can be conceived of.

The ease with which Linux may be ported to a variety of CPU architectures is a key contributor to the software’s widespread adoption. Linux was first developed for the Intel 80386, but it has now been ported to almost every CPU that has ever been made. The ARM chip that gives the Raspberry Pi its power is included in this.

6. Classic Gaming

If you’re a fan of retro video games, you might be shocked to learn that Linux and open source software are the driving forces behind the resurgence of older titles.

Emulators that are freely available to the public, such as MAME, Nestopia, and Stella, make it possible to play retro video games on a variety of systems, including Linux.

Not only have volunteers working on open-source software acknowledged the importance of retro video games, but even businesses have begun to include Linux and open-source emulators into their products and services. According to Omg! Ubuntu, if you own a NES Classic, you already have a system that is capable of running Linux. You can create your very own retro gaming console with nothing more than a Raspberry Pi and some do-it-yourself ingenuity.

Today, Linux has a plethora of practical applications.

Linux is not only a pastime for computer hackers; rather, it has a wide variety of applications in the real world, both for business and for entertainment. You name it, and someone has probably used Linux to accomplish it, from managing websites and databases to playing old video games.

If you can conceive it, someone has probably used Linux to do it. But how did Linux grow so ubiquitous? There are several technological advancements that have made it simpler for people to disseminate Linux.
