What is Linux?
Linux is a Unix-like, open source and community-developed operating system (OS) for computers, servers, mainframes, mobile devices and embedded devices.
Linux is highly configurable and depends on a modular design that enables users to customize their own versions of Linux. Depending on the application, Linux can be optimized for different purposes.
Linux distributions
A Linux distribution, sometimes known as a “distro,” is a compilation of the Linux operating system and a number of additional programmes and tools. The Linux kernel serves as the foundation for each distribution, which may also have its own user interfaces, package managers, and software repositories. The most well-known Linux distributions are Mint, Fedora, Ubuntu, and Debian.
