Operating System — Linux
Linux is one of popular version of UNIX operating System. It is open source as its source code is freely available. It is free to use. Linux was designed considering UNIX compatibility. Its functionality list is quite similar to that of UNIX.
Components of Linux System
Linux Operating System has primarily three components
Kernel − Kernel is the core part of Linux. It is responsible for all major activities of this operating system. It consists of various modules and it interacts directly with the underlying hardware. Kernel provides the required abstraction to hide low level hardware details to system or application programs.
System Library − System libraries are special functions or programs using which application programs or system utilities accesses Kernel’s features. These libraries implement most of the functionalities of the operating system and do not requires kernel module’s code access rights.
System Utility − System Utility programs are responsible to do specialized, individual level tasks.
Kernel Mode vs User Mode
Kernel component code executes in a special privileged mode called kernel mode with full access to all resources of the computer. This code represents a single process, executes in single address space and do not require any context switch and hence is very efficient and fast. Kernel runs each processes and provides system services to processes, provides protected access to hardware to processes.
Support code which is not required to run in kernel mode is in System Library. User programs and other system programs works in User Mode which has no access to system hardware and kernel code. User programs/ utilities use System libraries to access Kernel functions to get system’s low level tasks.
Basic Features
Following are some of the important features of Linux Operating System.
Portable − Portability means software can works on different types of hardware in same way. Linux kernel and application programs supports their installation on any kind of hardware platform.
Open Source − Linux source code is freely available and it is community based development project. Multiple teams work in collaboration to enhance the capability of Linux operating system and it is continuously evolving.
Multi-User − Linux is a multiuser system means multiple users can access system resources like memory/ ram/ application programs at same time.
Multiprogramming − Linux is a multiprogramming system means multiple applications can run at same time.
Hierarchical File System − Linux provides a standard file structure in which system files/ user files are arranged.
Shell − Linux provides a special interpreter program which can be used to execute commands of the operating system. It can be used to do various types of operations, call application programs. etc.
Security − Linux provides user security using authentication features like password protection/ controlled access to specific files/ encryption of data.
Architecture
The following illustration shows the architecture of a Linux system −
The architecture of a Linux System consists of the following layers −
Hardware layer − Hardware consists of all peripheral devices (RAM/ HDD/ CPU etc).
Kernel − It is the core component of Operating System, interacts directly with hardware, provides low level services to upper layer components.
Shell − An interface to kernel, hiding complexity of kernel’s functions from users. The shell takes commands from the user and executes kernel’s functions.
Utilities − Utility programs that provide the user most of the functionalities of an operating systems.

Best Linux Distributions That are Most Suitable for Beginners
Last updated March 25, 2021 By Aquil Roshan 326 Comments
Brief: It’s easy to get overwhelmed by the list of Linux distributions available. In this article, we will mention the best Linux distros for beginners.
Let’s face it, Linux can pose an overwhelming complexity to new users. But then, it’s not Linux itself that brings this complexity. Rather, it’s the “newness” factor that causes this. Not getting nostalgic, but remembering my first time with Linux, I didn’t even know what to expect. I liked it. But it was an upstream swim for me initially.
Not knowing where to start can be a downer. Especially for someone who does not have the concept of something else running on their PC in place of Windows.
The first thing that confuses a newcomer is that Linux is not a single operating system. There are hundreds of Linux distributions. We have covered why there are so many Linux in detail, so I am not going to discuss it again.
Here are a few lists of Linux distributions based on different criteria:
In addition to that, there are distributions that cater to the needs of newcomers especially. So, here, we shall focus on those options.
Best Linux Distros for Beginners
Please remember that this list is no particular order. The main criteria for compiling this list is the ease of installation, out of the box hardware support, ease of use, and availability of software packages.
1. Ubuntu
- Easy to use
- Unique user experience
- Huge collection of software applications available through the software center
- Essential tools pre-installed
You must have heard about Ubuntu — no matter what. It is the most popular Linux distribution overall. Not just limited to servers, but also the most popular choice for Linux desktops.
It is easy to use, offers a good user experience, and comes pre-installed with essential tools to get a head start. Of course, Ubuntu managed to “simplify” the Linux experience years back and that is the reason why it is still so popular even with several impressive Linux distributions available right now.
Ubuntu offers a very convenient installation procedure and ensures best hardware compatibility when compared to some other non-Ubuntu based Linux distributions.
The original Ubuntu relies on GNOME desktop. Even though it is easy to use, it may not prove to be a familiar user interface if you’re coming from the Windows platform. In that case, you can try out some official flavors of Ubuntu like Kubuntu, Lubuntu to get a Windows-like user interface.
Ubuntu has a great documentation and community support. Ubuntu forums and Ask Ubuntu provide an appreciable quality support in almost all aspects regarding Ubuntu. You should easily find answers to common issues and even if you notice something new, the community will help you out troubleshooting.
2. Linux Mint
- Familiar user interface with Windows
- Performs great with older hardware
- Some improvements over Ubuntu
Linux Mint is arguably the best Ubuntu-based Linux distribution suitable for beginners. Yes, it is based on Ubuntu, so you should expect the same advantages of using Ubuntu. However, instead of GNOME desktop, it offers different desktop environments like Cinnamon, Xfce, and MATE. In fact, Linux Mint does a few things better than Ubuntu.
Not just limited to the familiar user interface, which will be a bonus for Windows users. It provides an impressive performance with minimal hardware requirements, especially with Xfce or MATE desktop environment.
It also uses the same software repository as Ubuntu. You don’t have to worry about the availability of software to install.
Linux Mint is a fantastic Windows-like distribution. So, if you do not want a unique user interface (like Ubuntu), Linux Mint should be the perfect choice.
The most popular suggestion would be to go with Linux Mint Cinnamon edition. But, you can explore whatever you want. Also, you might want to look at our tutorial to install Linux Mint 20 from USB.
3. Zorin OS
- Windows-like user interface
- Intuitive user experience
- Easy to use
- Ultimate edition available with a lot of pre-installed goodies and Lite edition for older computers
Zorin OS is yet another impressive Linux distribution that offers a similar user interface to Windows. It may not be the most popular choice but being an Ubuntu-based distribution, it is perfectly suitable for beginners while offering many cool features as well.
Zorin OS is an Ubuntu-based distribution but feels highly polished. In my opinion, it is perfectly tailored for former Windows users who want a similar look and feel but something beautiful.
No wonder why Zorin OS is one of the most beautiful Linux distros out there.
The ultimate edition of Zorin OS is worth spending if you need all the pre-installed goodies (fun games, office suite, and some additional features). But, the free edition works like a charm as well.
You will also find a “Lite” edition which is suitable for old hardware that needs to be revived.
4. Elementary OS
Now that I mentioned a beautiful Linux distribution above, elementary OS is actually the most popular good-looking Linux distribution that takes inspiration from macOS.
Even though it is not a “macOS clone” in any aspect, it tries to focus on the user experience similar to how macOS does (or should). If you are coming from the Apple ecosystem, you would love to try elementary OS for sure.
Again, it is based on Ubuntu, so you get all the benefits of it along with a rich user experience.
Elementary OS features the Pantheon desktop environment. You can immediately notice the resemblance to macOS desktop.
The operating system is zero intrusive so you can really focus on your work. It comes with a very small number of pre-installed software. So, any new user will not be repulsed by huge bloat. But it’s got everything you need out of the box. The App Center is also unique when compared to other Linux distributions.
You will find some elementary OS tailored applications and can choose to pay the developer through the software store as well.
Experience wise, Elementary OS is really a great piece of software.
5. Linux Lite
Linux Lite is yet another Ubuntu-based distribution that is easy to use. It is specifically tailored as a lightweight distribution with some pre-installed applications that are not resource-heavy.
Linux Lite is perfectly suitable for Windows users with a similar user interface featuring the Xfce desktop environment. Compared to its previous iterations, Linux Lite has improved the user experience. Even though it isn’t meant to provide you the most modern experience, it still looks great as a desktop OS.
6. Manjaro Linux
- Not an Ubuntu-based distribution
- Arch-based Linux distribution
- Presents a learning curve
If you want to take up a challenge with a learning curve and want to try something else other than a distribution based on Ubuntu, Manjaro Linux is the best bet.
It is based on Arch Linux but tailored as a beginner-friendly distribution. Of course, considering that it follows a rolling release update cycle, you might end up with a broken system (even though that does not happen all the time). But, you have to compromise on the reliability when compared to any Ubuntu based Linux distribution mentioned in this list.
You also get a wide range of choice to install a variety of software tools. There’s also AUR, which is a community-maintained repository for software that may not be available for Manjaro officially.
If you want to know more about it, you may want to check out our detailed review of Manjaro Linux.
Manjaro Linux offers different desktop environments like XFCE, KDE, Gnome, Cinnamon and a host of more desktop environments. So, you get a lot of choices.
7. Pop!_OS
- Improved user experience when compared to Ubuntu
- Extra out-of-the-box features like Auto window tiling to help with fast multi-tasking
Pop OS is probably the best Ubuntu-based Linux distribution if you’re not looking for a lightweight Linux distribution.
It provides a polished and snappy experience when compared to Ubuntu GNOME edition. You also get some interesting features like automatic window tiling, window stacking, and a few more with Pop OS.
You also get a vanilla GNOME experience on Pop OS when compared to Ubuntu. However, unlike some other options, it does not officially support other desktop environments out of the box. So, if you do not like GNOME, you may have to manually try other desktop environments as an experiment. You might find the review of Pop OS 20.04 useful to explore more about it.
8. Peppermint OS
Peppermint Linux is an interesting choice for beginners who prefer to use web applications as local applications using the out-of-the-box integration with Ice.
It is based on Ubuntu, so along with all the goodies of Ubuntu it features a few extra options to give you a head start. It isn’t pitched as a lightweight distro, but it works quite well with older hardware as well.
9. Deepin
If performance or hardware requirement does not bother you, Deepin OS will be an interesting pick. It is known for its eye-candy user interface that is one of the most gorgeous Linux distributions out there.
Of course, it suffers from performance issues if you do not have a decent modern hardware configuration. But, if it works well on your system, it is easy to use and offers plenty of software tools to get started.
Some might mention that just because it is a project with based out of Mainland China, you need to avoid it. So, if you have an issue with that, you might take a look at UbuntuDDE (which is basically Ubuntu + eye-candy visuals of Deepin)
Your choice for the best Linux distro for beginners?
Linux might come with a tiny learning curve, but that’s not something anybody ever regretted. Go ahead, you will love it like I do!
To give you a head start, I would recommend you to follow Ubuntu 20.04 installation guide and refer how to install a distro from USB.
