What are the basic elements of Linux

When we turn on our computer/laptop, we get a screen where we can perform several things such as editing a document, surfing the internet, playing videos, downloading apps, etc. We need to operate on our electronic device with the Operating System(OS). Many of us have used many common OSs, such as Windows, Apple OS, but we’re going to talk about LINUX here.

Linux is an open-source Unix culture, including the Linux Kernel-based operating systems. On September 17, 1991, it was initially published by Linus Torvalds. It is a free and open-source operating system. Under the GNU General Public License, the source code can be updated and distributed to anyone commercially or non-commercially.

Linux was initially designed for personal computers and was eventually used on other computers, such as servers, mainframe computers, supercomputers, etc. Linux is also used today in embedded systems such as routers, controls for automation, TVs, digital video recorders, video game consoles, smartwatches, etc. Android(operating system) is the most tremendous success of Linux; it is based on the Linux kernel that runs on smartphones and tablets. Linux has the highest user base of all general-purpose operating systems because of Android. Generally, Linux is bundled inside a Linux distribution.

Evolved from Unix, Linux offers users a low-cost, safe way to handle their data center resources. Linux can be tricky to understand because of its open-source architecture and includes command-line interface experience and the expectation of inconsistent documentation.

But even though Linux has been providing reliable, stable OS tasks for decades, the general public is not all that familiar with the word Linux. Do you wonder what it’s all like with Linux operating systems? Continue reading to find out.

You first need to understand what an operating system or OS is for a computer. An OS is the programming code on a physical computer that controls the hardware. It exists between your software and your hardware as a layer. Most people who write software do not want to know how to connect with a graphics card or address a CPU in an assembler. An OS serves as a middleman, such as Linux or Windows.

In short, Linux is an OS. But Linux has several features that set it apart from Microsoft and Apple OSes and licensing options. It helps to understand the various Linux OS components and the related terminology to understand what Linux can do.

Operating system

All software inside a machine is run and controlled by an operating system. The OS is accessed via an API, command-line interface (CLI), or GUI to execute programs.

The OS decides what applications should run and when; how much memory each application needs; discharges batch jobs to minimize the number of applications running in the background, and tracks input and output to any attached hardware—and from.

Windows and Mac are closed, proprietary OSes managed by each business through its in-house developers of software. As the leading developer of the Linux OS and its modules, Linux — established in the 1990s as a free alternative for PC users — relies on interested coders and individual contributors.

GNU General Public License

The GNU General Public License (GPL) sets out, much like a vendor software license, the conditions under which free software can be used, copied, and modified. The GPL’s purpose is to ensure that free software stays open and does not ultimately become a closed source or proprietary source. The Free Software Foundation is the owner of the license.

Under the GNU GPL, with a few stipulations, users can copy Linux code verbatim and apply it to their internal systems. Any copied code must include a copyright notice, intact GPL notes, a warranty disclaimer, and a copy of the GPL to remain in compliance. Suppose you plan to redistribute Linux OS components under the GPL. In that case, it is essential to include all previous details and to log any changes.


The core of a computer’s OS is a kernel. Its primary purpose is to serve as a bridge between the OS and the hardware; computer control, networking, memory management, and file systems are also helped by the kernel.

Kernels use system drivers to perform actions. These drivers contain unique pieces of code corresponding to the operating system’s computer. Character device drivers, block device drivers, and network device drivers are the three primary driver types.

The Linux kernel was introduced in 1992 and is split into multiple subsystems: memory management, network stack, process control, system call interface, virtual file system, arch, and device drivers.

The Linux kernel had 27,8 million lines of code in January 2020. As the kernel is continuously maintained and updated by the open-source community, it is an excellent server infrastructure option that needs real-time maintenance. It is also possible to port the Linux kernel into your OS and set it to run live updates.


The elements of the Linux OS are open source. Still, the various distributions are ideal for different deployment modules, infrastructures, and use cases. Each distribution—or distribution—is a Linux OS version bundled with customizable management tools, dedicated software, or installation programs.

Hundreds of distributions exist, but Fedora, Red Hat Enterprise Linux, Ubuntu, OpenSUSE, and Oracle Linux are the most popular ones. Debian and Slackware have more community-focused versions.

Suppose you can’t invest in-house time or talent configuring the OS or advanced functionality. In that case, vendors provide service-level agreements (SLAs), specialized add-ons, and consulting for particular industries and use cases. In this model, suppliers, not the source code itself, make money from additional services and tools.


The OS is loaded into a computer’s memory by a bootloader, also known as a boot manager. The basic I/O framework runs some necessary tests once you restart or power up your computing infrastructure and then launch the master boot record to run the OS. If you are running a Mac or Windows OS, a bootloader is automatically installed on the device.

With Linux, to run any distribution, you must install a separate bootloader. Two primary options are available: GRUB and LOAD Linux (LOADLIN). If there are several OSes in the data center or don’t spend a lot of time using Linux, LOADLIN is better. If you want more versatility in your operating system and want the ability to change boot options from the command line, you can use GRUB.

Linux commands are used to execute one or more functions, such as copying, pasting, searching, etc. to run any program commands; the use of commands tasks can be efficiently and effectively typed in a shell; this is like a link between the core Linux and us, which transforms the human code to be executed by hardware.

To find something in a file, we can execute the code, as well as we can write code to implement the more complex regulations, such as we can run a command on the output of one order, for which we need to use the “|” (pipe separator) between two or more powers. This pipe operator, in other words, functions as a joint for both commands. We have the examples below of both single orders and the collective of multiple commands using the pipe.

Usually, most of us use the desktop operating systems are bundled with our machines, and we seldom ask why operating systems need to be modified. Few people are interested in learning a new operating system and rarely question what Linux is because they feel that the work is just fine with their current operating system.

However, how much time is wasted in the battle against popular OS issues, including malicious software such as viruses, regular OS crashes, and the resulting expensive fixes, is not always evident. Don’t forget that most operating systems often charge a fee for a license.

Perhaps your current option of OS is not really really doing the job well. You may just want to think about Linux and whether it provides a better, free alternative if you are tired of paying for an operating system and hate the constant expensive maintenance you have to do on your current OS. There is no charge for trying Linux, and many users would consider Linux to be the desktop computer’s most stable operating system.

Because of Linux’s open-source collaborative nature, there is really no charge for trying Linux. On an infinite number of machines, you can install the OS free of charge without paying anything to license it. For both the server and the desktop versions of several Linux distributions, this is the case.

On the other hand, many Linux distributions are entirely free and provide open-source server applications, so you can browse web pages without paying any licensing fees. In fact, having a fully functioning Linux web server up and running is just a couple of clicks away.

It is also easy to argue that Linux software makes life easy for system administrators since Linux is more stable. It means that you don’t have to closely watch your server every day, so you can rely on it to run without a problem. Also, without affecting the entire Linux OS, you can sometimes restart individual services because of Linux’s design.

An operating system, by definition, is a tool you need to be able to rely on. The stability that Linux brings can be game-changing if the cost is not the most significant consideration for you. Wondering what the greatest benefit of the Linux operating system is? Maybe the main reason for embracing Linux is its intrinsic stability and general immunity to viruses, malware, and other random operational system problems.

Server reboots are a specific concern for sysadmins. Because of their reliability, Linux allows sysadmins to prevent reboots to no small degree unless the kernel is modified. In fact, many Linux servers will run for years, never seeing a reboot. This will often be viewed by sysadmins as a sign of Linux’s reliability.

The various Linux editions, or distributions, can be very varied. They can be intended for desktop use or built to be used as applications for servers. Some Linux distributions concentrate on expert users, whereas other Linux distributions are quick enough for beginners to use. Often known as distros, most Linux versions can be downloaded for free and burned for installation on an optical disk or USB drive.

There is a virtually infinite range of distributions of Linux. Ubuntu is often the default option for desktop Linux users. Still, Fedora, Arch, Linux Mint, Debian, and OpenSUSE are also common choices. Thanks to Ubuntu Unity, Ubuntu is one of the most modern. At the same time, KDE, which includes openSUSE, has a more traditional Linux look.
