What is Linux?

Linux is an Operating system, just like Windows and macOS. It is one of the most popular Operating systems in the world. It is the best known and most used open-source Operating system.

In fact, Linux is a kernel, not an operating system. For example, Android is built on top of the Linux Kernel. As the Linux kernel is open-source, the source code of the Linux kernel is available in public to view and edit as required.

Why Linux?

All the fastest supercomputers in the world run on Linux. 96.3% of the top 1 million web servers run on Linux. 86% of all smartphones (Android) are powered by Linux.

Linux is one of the most loved operating systems as per StackOverflow insights.

In the cloud and DevOps world, many new tools are developed and used in Linux environments. Many tools were first developed and released in the Linux environment the lately supported windows and other operating systems. for Example Docker, Docker was first developed and released in the Linux Operating system then due to the rise in popularity of docker they were released for Windows and other operating systems.

In Desktop Environments we have GNOME, Mate, Xfce, KDE, and many more these environments are installed based on the Operating system development requirements. Each Desktop Environment has some built-in applications.
