What is Linux: Everyone knows about what Linux is and its usefulness. But those people who have not used it to date, we will tell those people about Linux.
It is also an operating system of the computer like Windows. Which was released in 1991, and today it is available completely free.
Linux is commonly used on all devices. At the same time, they are also being used in the entire Internet Server, and due to it being completely safe and error-free, it is being used a lot. You will get complete information about it in this post.
Come friends, now we start with Linux if you want to get complete information about it. So you read this post from beginning to end, we hope that in this post you will be given complete information about Linux.

What is Linux?
Linux is Unix Based Operating System. We all are familiar with other operating systems like Microsoft Windows, Apple Mac OS, iOS, Google Android, etc.
Similarly, Linux is also an operating system. Linux is available on the World Wide Web. Many companies make Linux’s Easy to Use Version Red, Head, Coral, and Mandrake Version.
Red Linux is the popular version that comes with the GNOME Desktop Environment. GNOME is very good at working. It helps to display the pictures on the screen.
It is the open-source code of the operating system. Linux can be copied, modified, and redistributed with some restrictions.
It is open-source code, so the operating system can be customized to meet the personal needs of various networks.
Linux is so popular among users because it is very flexible. Advantages like Solid, Mature Operating systems like Unix are available in Linux and it has many advantages anyway because or absolutely FREE.
Linux has been around us since the 90s. Can be used from wristwatches to supercomputers. It is everywhere in our phones, laptops, PCs, cars, and even refrigerators. It is very famous among developers and general computer users.
Basic Features of Linux
1. Multiuser Capability
It is a Multiuser System. This means that multiple users can access all its system resources such as memory, hard disk, etc. at the same time. But different terminals have to be used to operate them.
It is a multitasking system which means that more than one function can be performed simultaneously by dividing the CPU time wisely.
Portability does not mean that it is small in file size or can be carried in pen drives or memory cards. It means that it supports different types of hardware.
It provides security in three ways. Converts the encryption file into an unreadable format by assigning an authenticating password and login ID, assigning permissions to read, write, and execute authorization.
5. Live CD/USB
It Distros provides Live CD/USB. So that users can run or try it without having to install it.
6. Open Source
It Code is freely available to all and it is a Community Based Development Project.
7. File System
It provides a Hierarchical File System in which files and directories are arranged.
8. Application support
It has its own software store from where users can download and install many applications.
9. Support’s customized keyboard
It is used all over the world so it supports keyboards in different languages.
10. Graphical User Interface (X Window System)
It is a command line-based OS but it can be converted into GUI based on package installation.
Who is the Owner of Linux?
Since the licensing of Linux is open source. Therefore Linux is freely available to anyone. But still, the trademark of the name “Linux” goes to its creator, Linus Torvalds.
The copyright of the source code of Linux OS goes in the name of many individual authors. Therefore it is collectively placed under the GPLv2 license.
Because a very large group has a hand behind Linux. Those who have contributed in this which took many years to develop.
In such a situation it is not even possible to contact them individually, so the license of Linux has been included under GPLv2 which includes everyone’s consent.
How did Linux get started?
Linux was created by Linus Torvalds in 1991. When he was a university student at the University of Helsinki.
Torvalds built Linux as a free and open source alternative to Minix OS. Which was another Unix clone, and which was mainly used in academic settings.
He first thought of naming it “Freax” but the administrator of the server that Torvalds had chosen to distribute his original code. He named his directory “Linux” which was a combination of Torvalds’ first name and Unix. This name was so good to hear that it was not changed anymore.
Components of the Linux System
There are mainly three components of the Linux Operating System.
2 System Library
The kernel is the core part of Linux, it is responsible for all the major activities in the operating system. It contains many other modules, and they interact directly with the underlying hardware.
Kernel retains all the information of low-level hardware details until system or application programs. In simple words, like kernel abstraction. deals.
2. System Library
System libraries can be called those special functions or programs using which we can access the features of application programs or system utility kernel.
Implement almost all the functionalities of the operating system. And they do not even require the kernel module’s code access rights to do so.
3. System Utility
The program responsible for performing other specialized, and individual-level tasks is called system utility.
