What is Linux, its history and advantages

Do you know what Linux is? What can we use this Linux operating system for? Whether you take any gadgets from smartphones to cars, supercomputers or your home appliances, this Linux operating system is popular everywhere. We may not have much information about it, but we are always using it.

It has been more than 30 years since Linux came. It came first among us in the mid 90s. And since then, due to its usefulness, it has fully maintained its ambition in all devices and will continue to do so. Those who have used Linux operating system before, they will know about its utility but those who are not yet familiar with it, then I want to tell those people that we use it in all devices Which we use with common means. With this, it is used in almost entire internet servers, even in stock exchanges.

Mainly due to this more reliable, secure and error-free operating system, everyone wants to use Linux kernel. And one thing it is completely open source and also free, which helps developers to customize it in their own way. So today I thought why should you all be provided complete information about what Linux is so that you too have complete knowledge about this best open source operating system. So, let's start delaying and know what Linux is.

Linux is a very popular version of the UNIX operating system. It is an open source software as its source code is freely available in internet. With this, you can use it absolutely free, to say that it is completely free.

Linux was designed keeping in mind the compatibility of UNIX. Hence its functionality list often resembles that of UNIX. Being Linux open source, developers can customize it according to their needs. With this, it is a very reliable operating system for computers.

Who is the owner of Linux?

Since Linux licensing is open source, Linux is freely available to anyone. But still the trademark "Linux" goes to its creator, Linus Torvalds. The copyright of the source code of Linux OS goes in the name of many individual authors, so it is collectively kept under the GPLv2 license.

Since Linux is behind a very large group who have contributed to it and which took years to develop, it is not possible to contact them individually, so the license of Linux was 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, another Unix clone and used mainly in academic settings.

He first thought of naming it as "Freax", but the administrator of the server whom Torvalds had chosen to distribute his Origonal code, named his directory as "Linux" which was a combination of Torvalds' first name. And Unix. It was so nice to hear the name that it was not changed later.

Linux System Components

If seen, Linux Operating System mainly consists of three components.

1. Kernel - This is the core part of Kernel Linux. It is responsible for all major activities happening in the operating system. Other modules are meager and involve direct interaction with the underlying hardware. Kernel prevents the information of low-level hardware details from reaching the system or application programs or behaves like an abstraction.

2. System Library - System libraries are called special functions or programs which are used to access the features of application programs or system utility Kernel. These libraries implement almost all functionalities of the operating system and they do not even need kernel module’s code access rights to do so.

3. System Utility - System Utility is those programs that are specialized, and responsible for performing individual level tasks.

Advantages of linux

Here I am going to tell you about some very important features of Linux Operating System.

1. Portable - Portability means that this software can run the same way in all types of hardware. Linux kernel and application programs support almost all hardware platforms.

2. Open Source - Linux source code is freely available and is a community-based development project. Multiple teams work by collaboration so that the capacity of the Linux operating system can be increased and hence it is always evolve.

3. Multi-User - Linux is a multiuser system which means multiple users res all its systems at the same time.to use ources such as memory / ram / application programs.

4. Multiprogramming - Linux is a multiprogramming system which means that multiple applications can run simultaneously at the same time.

5. Hierarchical File System - Linux provides a standard file structure so that system files / user files can be easily arranged.

6. Shell - Linux also provides a special interpreter program which has to execute the commands of the operating system. Along with this, it is also used to do other different operations, call application programs.

7. Security - Linux also provides very good security feature to users such as password protection / controlled access to some specific files / even data encryption etc.
