Linux Tutorial for Beginners and Advanced

Linux is a kernel, the bare minimum necessary to run a computer. A kernel is a computer program that handles input and output requests from various software on your computer and translates that data to the CPU for processing. That is, your commands are translated through the kernel and go to the CPU, and after the process, your desired response is outputted to your monitor or any other output device. An operating system is created with the kernel and more software, packages, etc. Be it Windows, Linux, or OS X.

Operating systems for the world's computers are notoriously unkind. For every market-leading operating system, such as Windows and macOS, there are dozens of obscure alternatives for even niche takers. The operating system market is actively resisting the dominance of a single entity. In light of this competitive landscape, it may be a surprise that Linux, a free and open-source operating system developed by a group of passionate volunteers, is one of the world's most widely used operating systems today. Many people use it every day, probably without knowing it. Learn what Linux is, why it has been so successful, and what its future holds.

History of the operating system Linux

Linux is an open-source operating system created by a developer named Linus B. Torvalds in 1991. Linux's name comes from the fact that the system consists of many different programming tools that work together like "a bunch of Lego bricks." Linux was created as a replacement for another operating system called Minix. Torvalds originally planned to use Minix on his computer but could not do so due to restrictive licensing policies. Therefore, he started building a free and open-source alternative operating system from scratch.

Early on, Linux was used almost exclusively by programmers in the academic world. Companies use operating systems only for very specialized applications. Not I was widely accepted among average computer users. However, in 2001, the popularity of Linux started to increase significantly. That's when Linux developers created a version of the operating system that ran on Intel-based computers. It later became known as the "Linux kernel," and its popular version is still known as the Linux kernel.

What is Linux OS?

Linux is a kernel, although it is also used to designate an open-source operating system based on the Unix operating system. Still, it is not a descendant of it but a clone. Linus Torvalds originally wrote Linux, but he later released his code so other programmers could improve and extend it. These programmers shared their code with the world, and open-source Linux was born. Linux does this for everything from desktop computers to supercomputers, mobile phones, and spaceships.

Advantages and disadvantages of the operating system Linux

Linux is an open-source OS operating system that has many advantages. The most significant advantage of using Linux is that it is free to download and use. This means there are no ongoing costs once you install Linux on your device. Also, it doesn't matter what kind of computer you have: Linux runs on Macs, PCs, laptops, and more. Linux is also very secure. This is because many developers are always working to protect against hacker attacks. Linux allows you to adjust certain settings to be more efficient. For example, you can change how data is stored on your device and how often your device automatically updates apps. Another benefit of using Linux is that it can be used for many different tasks. This is because many Linux variants can be used for multiple applications.

A significant disadvantage of using Linux is that some programs used by Windows and macOS users will not work. This includes iTunes, QuickBooks, some email applications, and some forms of Adobe programs. However, many Linux variants integrate these features into their operating systems.

Why is Linux OS popular?

Linux is widely popular among developers and system administrators. Linux's open-source model allows them to freely share code, learn from each other, and collaborate on projects. In many cases, this means that Linux has been perfected over time, the product of the efforts and insights of thousands of the industry's best and brightest. Since Linux is open source, it is considered a safe and ethical choice for government and institutional use. It also has a fully transparent code base, allowing easy inspection of potential vulnerabilities. Additionally, Linux is free to download and distribute, making it affordable for businesses of all sizes. And although Linux is considered an enterprise-grade operating system, it also has a wide range of usability and customization options.

Where do you get Linux?

Depending on who you ask, Linux can be found in many different places. Depending on how Linux is defined, the operating system is available on many devices and pieces of software. For example, Android is based on a Linux kernel. So is the OpenSSH server. And Linux is used on Apple's Macintosh computers and its macOS operating system. These are the places where Linux can be found:

Mobile: Android, Firefox OS, Selfish OS, Ubuntu Touch
Desktop computers: Apple computers and PCs
Linux server
Others: Smartwatches, Smart TVs (WebOS and Tizen), Cisco routers, Tesla cars, and more.

A promising future of the Linux OS

Although it has not conquered the PC field, Linux has a bright future. It is difficult to predict the end of any technology or product. But one thing's certain: Linux's popularity will be around for a while. With all the investment and momentum behind Linux, the open-source operating system can expand into new markets and use cases. As a freely distributed and open-source product, Linux can evolve rapidly, branching into innovative new operating systems.

Online tutorials and courses

The Linux operating system has revolutionized the way we use technology. Numerous businesses worldwide continue to use it now after using it for many years. Multiple items we use daily, such as mobile phones, watches, and even cars, also contain them. Linux has a fascinating history and will continue to play an important role in our daily lives. The next step is to try Linux now that you know what it is, why it's so well-liked, and where to find it.
