What Is Linux?
Linux is an open source operating system, which means that its source code is freely available to anyone who wants to use, modify, or distribute it. This openness has led to a vibrant community of developers and users who continually improve and expand upon the system. One key thing to note is that Linux refers to the kernel, the core component of the operating system, rather than the entire operating system itself.
When it comes to operating systems, you might be more familiar with Microsoft Windows or macOS. Linux, however, offers a different approach. It’s like having a toolbox with endless possibilities, allowing you to customise your system to suit your needs. Due to its secure and open nature, Linux has become one of the most widely used operating systems and has emerged as a powerful player in the world of CPU computing.

Linux also comes in various flavours, known as distributions or distros. Some popular ones include Ubuntu, Fedora, and Debian. Each distro has its own set of features and tools, catering to different use cases. If you need to install additional software, Linux offers a vast repository of free software that you can easily access and integrate.
Why Use Linux? The Power of Open Source
Now, you might wonder, “Why should I choose Linux over other operating systems?” The answer lies in the power of open source software. Linux’s open-source nature has contributed to its popularity, with a significant market share of approximately 3.19% in desktop operating systems as of August 2023, according to StatCounter.
Open source software, like Linux, is developed collaboratively by a global community of passionate individuals. This means constant updates, security enhancements, and an ever-expanding pool of software available at your fingertips. And the best part? It’s all free. Linux is also released under the GNU General Public License (GPL). This licence ensures that Linux remains open and accessible to the community. The Free Software Foundation advocates for the principles of free software, promoting user freedom and community-driven development.
Linux also excels in stability and security. With its robust permissions system and regular security and software updates, it’s a favourite choice for servers and mission-critical systems. Speaking of servers, let’s explore Linux’s history in that realm.
History of Linux OS
Linux’s journey began in 1991 when a Finnish student named Linus Torvalds, from the University of Helsinki, released the first version of the Linux kernel. Initially, it was a personal project, but it quickly gained attention and support from the open source community.
As Linux grew, it found its way into server rooms and data centres around the world. Companies like Red Hat and SUSE developed enterprise-grade Linux distributions, offering support and services to businesses. Linux became the backbone of the internet, powering websites, cloud servers, and more through its powerful server software.
Linux Kernel: The Heart of the Linux Operating System
At the core of every Linux operating system is the Linux kernel. Think of it as the conductor of an orchestra, coordinating all the different parts of your system.
The kernel manages hardware resources, communicates with your computer’s hardware, and ensures that software programs run smoothly. It’s the unsung hero of your operating system, working tirelessly in the background to keep everything running smoothly.
Pros and Cons of Linux OS
Linux has a lot to offer, but it’s not without its quirks. Let’s take a look at some of the pros and cons of using Linux.
Pros
- Open Source: You have access to the source code and can customise your system to your heart’s content.
- Stability: Linux is known for its stability, making it an excellent choice for servers and critical systems.
- Security: Regular updates and a strong permissions system contribute to Linux’s security.
- Variety: With numerous distros available, you can choose the one that best suits your needs.
Cons
- Learning Curve: If you’re new to Linux, there’s a learning curve, especially if you’re used to other operating systems.
- Software Compatibility: Some specialised software may not be available for Linux, though alternatives often exist.
- Hardware Support: While Linux supports a wide range of hardware, you may encounter issues with certain devices.
What Is the Difference Between Unix and Linux?
Unix is an operating system that dates back to the 1960s and served as the inspiration for Linux. Linux, on the other hand, is a Unix-like operating system that shares many of its principles and design concepts. Both are known for their stability and security, but Linux has the advantage of being open source, which has led to its widespread adoption and development.
Linux Distributions – Choosing the Right One
Now that you know the basics of Linux, it’s time to explore the world of Linux-based distributions. Every distribution is a complete operating system built around the Linux kernel that manages hardware and its processes. It also includes not only the kernel but a wide range of software packages, libraries, system utilities, desktop environments (in the case of desktop-oriented distros), and a package management system. Whether you are running Linux on a server or desktop operating environment, you can choose the distribution that aligns with your needs and goals. Choosing the best Linux distribution for your needs can make a significant difference in your Linux experience.
