The Basics of Linux
Linux is a free and open-source operating system that can be used for a wide range of purposes. Its flexibility, stability, and strong security make it ideal for server systems, mobile devices, and more. Linux is also known for a broad software library and an active community that provides support and updates.
Founded by Linus Torvalds in 1991, Linux was created as a free alternative to the popular MINIX UNIX clone. Torvalds initially shared the Linux kernel through internet groups, and he named it Freax after his first name and the word “freak.” However, Ari Lemmke, who ran the servers where the kernel was stored, didn’t think Freax was a good name, so he changed the name to Linux.
The Linux kernel is a core component of the operating system and handles the fundamentals of the computer, such as memory management and process control. The Linux kernel is the foundation for all other components of the operating system, which include the graphical user interface (GUI), application programs, and configuration and performance tools. While many Linux distributions share certain core software, each one is unique and combinations of software vary widely.
Most Linux distributions feature what is called a Live distribution, which allows users to run the operating system from a CD or USB drive without making any changes to their hard drive. This lets users test out the system and see if it’s what they’re looking for before committing to an installation. Some even offer a single-click installer for quick and easy installations.
Once Linux became more user-friendly, it gained momentum in the IT world and is now used on a variety of platforms and devices. For example, Android phones and Chromebooks use a version of Linux. In fact, most of the servers that power the internet use Linux.
Linux’s popularity continues to rise, as it offers a number of advantages over other commercial operating systems, such as the ability to run on a variety of different hardware types and the absence of licensing costs. In addition, many companies find that Linux is more secure than other OS’s and are less susceptible to attacks such as ransomware or viruses.
If you’re new to Linux, it may seem daunting to learn how to navigate its complex file structure and jargon. Fortunately, the Linux Foundation has put together a handy guide to help you get started. The guide outlines everything you need to know about the Linux kernel and its directory structure, as well as some basic commands you can use to perform common tasks. It also includes a list of the most important links and resources to get you started.
