What Is Linux?
Linux is a 100% open-source and free operating system based on Unix. It was built by Linux Torvads in 1991 as a hoppy project, but today it uses millions of devices globally. Linux works as a bridge between hardware and software. Enabling applications to run smoothly like windows or macOS. The Linux operating system is made up of several parts:
The Linux operating system is built up of different parts:
● Kernel – the core of the system that manages hardware and resources
● Shell – the interface where users run commands
● File system – organizes files and directories
● User applications – such as browsers, editors, tools
Due to Linux being open-source, anyone can view, modify, or distribute its source code. This makes it one of the most community driven technologies in the world.
Why Is Linux Used?
Linux is being used for multiple reasons such as – security, performance, stability and cost-effectiveness. In fact over 90% of cloud servers in the world use Linux. Let’s understand more about it.

Linux has many versions known as distributions or distros. Each distro is made for specific users.
● Ubuntu – best for beginners
● Debian – stable and reliable
● CentOS / Rocky Linux – used in servers
● Fedora – for developers
● Kali Linux – for cybersecurity
Because users can choose a distro based on their needs, Linux becomes more versatile than any other OS
Where Is Linux Used?
Linux is used in almost every industry because of its flexibility. Here are some major applications:
1. Servers and Data Centers
Linux powers web servers, mail servers, application servers, and cloud servers.
2. Mobile Devices
Android, the world’s most popular mobile OS, is based on Linux.
3. Cloud Computing
Platforms like AWS and GCP rely on Linux as the primary operating system.
4. Cybersecurity and Ethical Hacking
Tools like Kali Linux and Parrot OS are built for penetration testing.
5. IoT Devices
Smart TVs, routers, CCTV cameras, and smart appliances use Linux internally.
6. Development and DevOps
Most CI/CD pipelines, automation tools, and container platforms run on Linux.
Conclusion
Linux is more than just an operating system. It is a global ecosystem that powers everything from smartphones to supercomputers.
