What is Linux Operating System?

We are all familiar with the most widely used operating system, ‘Windows.’ Because of the popular use of Microsoft Windows, the terms “Windows” and “Operating system” are frequently interchanged. We won’t be talking about Windows today; instead, we’ll be talking about the LINUX Operating System. Yes, LINUX is an operating system with the same features as a Windows operating system. However, there are some distinctions between LINUX, Windows, and a variety of other operating systems. We will study numerous characteristics, applications, and unique features of LINUX OS in this LINUX lesson.

What is Linux?

Unlike Windows, LINUX is an open-source operating system, which means it is free to download and use. It is based on the UNIX operating system, therefore its characteristics are extremely similar to those of UNIX. The LINUX Operating System is widely regarded as one of the most secure operating systems available. You’ve probably heard of LINUX-based Website Hosting plans; these plans are always more expensive than others since they use the LINUX operating system on the server, which provides more data security. Stay with us as we walk you through the various uses of LINUX in this LINUX lesson.


Evolution of Linux OS

Mr. Linus Torvalds, the creator of LINUX, was a computer science student who worked on the UNIX operating system. Linus was a big fan of UNIX, but he wanted it to be better. UNIX was a solid operating system at the time, but it wasn’t very adaptable to changes, therefore Linus’ suggestions for improvement were rejected by the UNIX team. Linus, on the other hand, didn’t stop there and created his own LINUX OS, which was based on UNIX but improved.

Especially considering the fact that Linus built the OS LINUX, there was no applications for it because it was a new operating system. Why would someone want to use an operating system that doesn’t have any software? It lacked even a File Manager. As a result, Linus began working with other developers to create software for his OS, and in 1991, he released the LINUX Operating System, which included some basic software. Its popularity grew over time, and it eventually became one of the most popular open-source operating systems.

LINUX OS is still not a major competitor in the OS market for large corporations, but it does have a niche. One of the reasons for its low popularity is that it is never pushed; it is an open-source operating system, and Linus Torvalds never attempted to sell LINUX, which contributes to its durability.


What does Linux include?

Kernel:

The OS’s main component. The OS will not function without it. The kernel is in charge of managing the system’s resources and interacting with the hardware. Memory, process, and file management are all handled by it.
System user space :

The administrative layer for system-level tasks like configuration and software install. This includes the shell, or command line, daemons, processes that run in the background, and the desktop environment.
Application:

A type of software that lets you perform a task. Apps include everything from desktop tools and programming languages to multiuser business suites. Most Linux distributions offer a central database to search for and download additional apps.

How does Linux work?

Linux was designed to be similar to UNIX, but it has since grown to run on a wide range of hardware, including phones and supercomputers. The Linux kernel, which manages hardware resources, and a set of software packages that make up the remainder of the operating system are included in every Linux-based OS.

Some common basic components, such as the GNU tools, are included in the OS. These programs allow the user to manage the kernel’s resources, install extra software, adjust performance and security settings, and more. The operating system is made up of all of these tools when they are combined. Because Linux is an open source operating system, different Linux distributions may have different software combinations.


Linux and open source

Linux is a free, open source operating system, released under the GNU General Public License (GPL). Anyone can run, study, modify, and redistribute the source code, or even sell copies of their modified code, as long as they do so under the same license.

Linux has become the largest open sources software project in the world. Professional and hobbyist programmers from around the world contribute to the Linux kernel, adding features, finding and fixing bugs and security flaws, and providing new ideas—all while sharing their contributions back to the community.


Linux gets its due attention

Because of its open source structure, the LINUX Operating System is very popular among programmers. Anyone can take the LINUX source code and use it to create their own operating system using the LINUX Kernel. The LINUX Kernel is the foundation for many modern operating systems, including Knoppix, Ubuntu, and others. Its popularity stems from its adaptability. There are thousands of LINUX-based operating systems on the market now, with many more to follow.


The benefits of using Linux

Linux is on its prime and will only get higher from now on. The future belongs to LINUX, that’s why we are also providing this LINUX tutorial to you all so that you would get familiar with this OS. There are many benefits of using LINUX over any other OS present in the market, let’s go through a few:

  1. LINUX is open-source and free, i.e. anyone can take its source code and can modify it.
  2. Its software base is increasing rapidly and most of them are also free to use and offer the same functionalities as of other paid software.
  3. LINUX Operating System is one of the secured OS ever, you don't even need an antivirus. And it is open-sourced so developers from around the world are continuously working on its security enhancement.
  4. LINUX OS is one of the best choices for servers, thanks to its robust nature. It is currently the most reliable and stable OS.
  5. It is used in a personal computer, mobile phones, smartwatches, etc.

Is it for me? Should I learn Linux Tutorial?

Users originally disliked using LINUX because, apart from its excellent security and stability features, it lacked a user-friendly interface. But, because to constant updates and input from users all across the world, it currently has a rather well-organized interface to which no one should have any difficulty learning. So, if you’re interested in testing out LINUX, you should go ahead and do so.


Unix Vs Linux: What Is Difference Between UNIX And Linux?

In this LINUX tutorial, we are trying to give you as much background information as needed to understand exactly why LINUX Operating System is so popular and a reliable option for the developers. We all know that LINUX is a child of UNIX OS but it is an improved version, so we have listed some important differences between these two which will help you understand better that WHY LINUX OS is cooler than UNIX. Have a look:

  1. LINUX is open-sourced but UNIX is not.
  2. LINUX gives free community supports whereas UNIX offers paid commercial support.
  3. LINUX comes with frequent updates and quick bug fixes whereas in UNIX bug fixes can take time as the updates are not very frequent.
  4. LINUX OS uses a 'BASH' shell but the UNIX shell is 'Bourne'. Linux default shell is BASH while the Unix shell is Bourne Shell.
  5. LINUX Operating System supports almost all file systems but UNIX can only deal with two to three file systems.
  6. LINUX based OS are Ubuntu, Red Hat, Android, etc. UNIX based OS are Solaris, HP-UX, Darwin, macOS X, etc.

How Hard is it to Learn Linux?

Learning the Linux operating system is not as difficult as we may believe. Linux is simple to learn if you are familiar with technology and have a basic understanding of the operating system’s syntax and instructions. You can pick between a GUI (Graphical User Interface) and a CLI (Command-Line Interface) in Linux. Well, just because you’re using a graphical interface doesn’t mean you can’t use commands on it; you can use it as a command line as well.
