What is Linux?
A Brief Overview
Linux is a free and open-source operating system that has been used for decades to power everything from small embedded devices to supercomputers. It is known for its stability, security, and flexibility, and it is used by millions of people around the world.
Distributions and Kernels
Linux is not a complete operating system on its own. Instead, it is a kernel, which is the core of an operating system. To create a complete operating system, Linux is typically combined with other free and open-source software, such as the GNU toolchain and libraries. The resulting combination is called a Linux distribution, and there are many different distributions available, each with its own strengths and weaknesses.
Some of the most popular Linux distributions include Ubuntu, Debian, Fedora, and CentOS. These distributions are all based on the Linux kernel, but they include different sets of software and configurations. This makes them suitable for different purposes. For example, Ubuntu is a popular choice for desktop users, while CentOS is a popular choice for server users.
