Linux is not just an operating system: it runs on servers, smartphones, supercomputers, cloud platforms and cybersecurity tools. Even if you don’t realize it, Linux is already part of your daily digital life.
In this guide, we will break down Linux in simple English so that complete beginners can understand it. You will learn what Linux is, how it works, its features, benefits, types and real-world applications.
Let’s explore it together!
What is the Linux operating system?
Linux is one open source operating system that manages computer hardware and software.
In simple words:
Linux is the brain of a computer.
Like Windows or macOS, Linux helps your computer:
- run programs
- manage files
- control hardware
- dealing with memory
- communicate with devices
The biggest difference is:
Linux is free and open source.
This means that anyone can use it, modify it and improve it.
That’s why developers, businesses and governments trust Linux, because it is transparent, secure and customizable.
History of Linux
Linux was created in 1991 by a student named Linus Torvalds.
He wanted a free alternative to expensive operating systems. What started as a small project grew into a global revolution.
Linux timeline:
| Year | Event |
|---|---|
| 1991 | Linux is being adopted by companies and servers |
| 1994 | First stable Linux version released |
| 2000s | Linux is being adopted by companies and servers |
| 2010s | Linux dominates smartphones (Android) |
| Today | Backbone of cloud and internet |
Today Linux supports:
- Google servers
- Amazon cloud
- Android phones
- supercomputers
- cybersecurity systems
Linux is everywhere.
How the Linux operating system works
Linux has a layered architecture. Think of it like a sandwich.
Linux components:
- Kernel – core of the operating system
- Shell – command interface
- System libraries – communication bridge
- Applications – user programs
What is the kernel?
The kernel is the heart of Linux.
It checks:
- CPU
- memory
- hardware
- processes
- security
Linux cannot run without the kernel.
Everything you do on Linux goes through the kernel.
Main features of the Linux operating system
Linux became popular because of its powerful features.
- Open source: Anyone can see and edit the source code. No hidden secrets.
- Security: Linux has strong permission systems. Viruses rarely affect it.
- Multi-user support: Many users can work safely on one system.
- Multitasking: Run many applications at the same time smoothly.
- Stability: Linux systems can run for months without crashing.
- Customization: You can change everything: interface, behavior, tools.
- Free to use: No license fees. Completely free.
Benefits of the Linux operating system
Linux is preferred by professionals for many reasons.
| Function | Advantage |
|---|---|
| Free | No costs for installation |
| Certainly | Strong virus protection |
| Quick | Lightweight performance |
| Flexible | Adaptable environment |
| Trustworthy | Ideal for servers |
| Open source | Community support |

Linux saves money and improves performance.
Disadvantages of Linux
No system is perfect. Linux also has limitations.
- Learning curve for beginners
- Some Windows software is not available
- Gaming support improves, but is limited
- Hardware driver compatibility issues
However, most problems are solved with modern Linux distributions.
Types of Linux Distributions (Distributions)
Linux has many versions mentioned distributions.
Each distribution is built for different needs.
Popular Linux distributions:
- Ubuntu – beginner friendly
- Linux Coin – Windows-like interface
- Debian – stable and reliable
- Fedora – advanced features
- Kali Linux – cybersecurity tools
- Arch Linux – advanced customization
For beginners, Ubuntu and Mint are the best choices.
Where Linux is used in real life
Linux isn’t just for programmers.
It manages critical systems around the world.
Real world use:
- Web servers
- Cloud computing platforms
- Android smartphones
- Smart TVs
- IoT devices
- Supercomputers
- Ethical hacking tools
- Software development environments
About 90% of internet servers Running Linux.
That shows his strength.
Linux vs Windows vs macOS
Let’s compare the major operating systems.
| Function | Linux | Windows | macOS |
|---|---|---|---|
| Price | Free | Paid | Paid |
| Security | High | Medium | High |
| Customization | Very high | Limited | Medium |
| Gaming | Improve | Best | Moderate |
| Speed | Quick | Moderate | Quick |
| Stability | Excellent | Good | Excellent |
Linux wins in terms of flexibility and control.
Basic Linux commands beginners should know
Linux uses terminal commands for control.
Here are essential commands:
ls → list files
cd → change directory
pwd → show current path
mkdir → create folder
rm → delete file
cp → copy file
mv → move file
sudo → run as admin
Learning commands gives you full power.
Is Linux difficult to learn?
No.
Linux just feels difficult at first.
Modern Linux is beginner-friendly.
Reasons why it’s easy today:
- graphical interfaces
- large online community
- free tutorials
- step by step guides
- distributions for beginners, such as Ubuntu
If you can use Windows, you can learn Linux.
