Do you know what is Linux ? 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. Even though we do not have so 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 utility, 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 because of this more reliable, secure and error-free operating system, everyone wants to use the Linux kernel. And one thing is that 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 is Linux .
What is Linux Operating System?
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 the Computer is very reliable Operating system for.
Who is the owner of Linux?
Since the licensing of Linux 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 created 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 this 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 collaborating so that the capacity of Linux operating system can be increased and hence it is always evolve.
3. Multi-User – Linux is a multiuser system which means that multiple users can use all its system resources such as memory / ram / application programs at the same time.
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.
Linux operating system features
1. Hardware layer – This hardware layer contains all peripheral devices (RAM / HDD / CPU etc).
2. Kernel – This is the core component of Os, which interacts directly with the hardware, with it providing low-level service to the upper layer components.
4. Shell – This is an interface of kernel, which hides the complexity of functions of kernel from users. These shell take commands from users and execute kernel’s functions.
4. Utilities – These are called those utility programs that provide all functionalities of operating systems to the user.

Windows Vs. Linux: Key Differences
|Different data drives such as C: D: E are used in Windows to store files and folders.||Linux uses a tree-like hierarchical file system.|
|Windows has different drives such as C: D: E||There are no separate drives here.|
|Hard drives CD-ROMs printers are considered devices||In Linux, printers such as Peripherals such as hard drives CD-ROMs are considered files.|
|There are 4 types of user account types 1) Administrator 2) Standard 3) Child 4) Guest||There are 3 types of user account types here 1) Regular 2) Root and 3) Service Account|
|Here the Administrator user has all administrative privileges||At the same time, only Root user is a super user in Linux and has all administrative rights.|
|Here we cannot put 2 files in the same folder with the same name.||File naming conventions in Linux are case sensitive. So you can keep two files of the same name in the same folder.|
|Windows contains My Documents default home directory||In Linux, the user / home / username directory is created for all users, which will be called its home directory.|
|These are Closed Source Software||These are Open Source Software.|
|These are not very secure, where Virus attack is common in Malware Worms.||They are very secure and there is no flow of these Virus attack here.|
|It is single user and multi tasking.||It is also Multi-User and Multi Tasking.|
What is distribution?
There are many different versions of Linux operating system which is suitable for all types of users. Here you have different versions for everyone from new users to hard core users. These versions are called distributions. All Linux distributions can be easily downloaded for free and can also be installed later by burning them to a disk.
Here you can see the most popular Linux distributions:
- Ubuntu Linux
- Linux Mint
- Arch Linux
All these distributions are mehud with different features and you should also choose them according to your needs.

Is Linux Operating System completely Virus / Malware free?
The answer is no. There is no OS in the world that is 100% immune to Viruses and Malware . But there has never been any widespread malware-infection in Linux yet, if we compare it to Windows.
It is also true that users using Linux OS are very few, if we compare it with Microsoft Users. By the way, the main purpose of malware or virus is mass destruction. In such a situation, no programmer will waste his precious time in this work, as the users are very few. This is why Linux does not have many Virus.
Linux is architecturally very strong and therefore it is very immune to security threats. Remember that Linux is Kernel and GNU / Linux is an OS.
Technically speaking, you cannot set up a Linux system without root password and without user password. This means that every user of Linux has a password except for ‘ Guest ‘. In Windows, a user can create a profile without a password.
Due to all these features, fear of Virus and Malware in the Linux Operating System is very less.
