What Is Linux

Linux is an open-source operating system like other operating systems such as Microsoft Windows

Apple Mac OS, iOS, Google android, etc. An operating system is software that enables the communication between computer hardware and software. It conveys input to get processed by the processor and brings output to the hardware to display it. This is the basic function of an operating system. Although it performs many other important tasks, let's not talk about that.

Linux is around us since the mid-90s. It can be used from wristwatches to supercomputers. It is everywhere in our phones, laptops, PCs, cars, and even refrigerators. It is very much famous among developers and normal computer users.


Evolution of Linux OS

The Linux OS

was developed by Linus Torvalds in 1991, which sprouted as an idea to improve the UNIX OS. He suggested improvements but was rejected by UNIX designers. Therefore, he thought of launching an OS, designed in a way that could be modified by its users.

Nowadays, Linux is the fastest-growing OS. It is used from phones to supercomputers by almost all major hardware devices.

This is one of the most asked questions about Linux systems. Why do we use a different and bit more complex operating system, if we have a simple operating system like Windows? So there are various features of Linux

systems that make it completely different and one of the most used operating systems. Linux may be a perfect operating system if you want to get rid of viruses, malware, slowdowns, crashes, costly repairs, and many more. Further, it provides various advantages over other operating systems

, and we don't have to pay for it. Let's have a look at some of its special features that will attract you to switch your operating system


It is secure

Linux supports various security options that will save you from viruses, malware, slowdowns, and crashes. Further, it will keep your data protected. Its security feature is the main reason that it is the most favorable option for developers. It is not completely safe, but it is less vulnerable than others. Each application needs to authorize by the admin user. The virus cannot be executed until the administrator provides the access password. Linux systems do not require any antivirus program.


A flexible operating system

Linux is a flexible OS, as, it can be used for desktop applications, embedded systems, and server applications. It can be used from wristwatches to supercomputers. It is everywhere in our phones, laptops, PCs, cars, and even refrigerators. Further, it supports various customization options.


Linux Distributions

Many agencies modified the Linux operating system and makes their Linux distributions. There are many Linux distributions available in the market. It provides a different flavor of the Linux operating system to the users. We can choose any distribution according to our needs. Some popular distros are Ubuntu, Fedora, Debian, Linux Mint, Arch Linux, and many more.

For beginners, Ubuntu and Linux Mint are considered useful, and, for the proficient developer, Debian and Fedora would be good choices. To Get a list of distributions, visit Linux Distributions


How does Linux work?

Linux is a UNIX-like

operating system, but it supports a range of hardware devices from phones to supercomputers. Every Linux-based operating system has a Linux kernel and a set of software packages to manage hardware resources.

Also, Linux OS includes some core GNU tools to provide a way to manage the kernel resources, install software, configure the security setting and performance, and many more. All these tools are packaged together to make a functional operating system.

How to use Linux?

We can use Linux through an interactive user interface as well as from the terminal (Command Line Interface). Different distributions have slightly different user interfaces but almost all the commands will have the same behavior for all the distributions. To run Linux from the terminal, press the "CTRL+ALT+T" keys. And, to explore its functionality, press the application button given on the left-down corner of your desktop.
