Introduction to Linux
Linux is an open-source, Unix-like operating system kernel that serves as the foundation for a variety of operating systems (distributions or distros) tailored for different types of users and use cases. Created by Linus Torvalds in 1991, Linux is designed for multitasking, multi-user operations, providing robust security, and system stability. It's highly customizable, making it a popular choice for servers, desktops, embedded systems, and supercomputers. For example, Linux runs on the vast majority of web servers worldwide, enabling websites and web applications to function. It's also the underlying system for Android, the most widely used mobile operating system. Another scenario showcasing Linux's versatility is its adoption in supercomputing, where its ability to be customized and scaled powers the majority of the world's fastest supercomputers.
