Chapter 1: What is Linux and Why Using It?
Strengthening almost everything from mobile phones, servers, and PCs, Linux is a standard operating system that people commonly use. Indeed, all over the world, several individuals use Linux in all fields and applications you can imagine. Linux has been around since the 90s. From your TV stick to the fridge and everything, Linux runs everything. And much of the internet has support from Linux. Since the computer operating system has powered several innovations, many scientific breakthroughs have Linux to thank. Even though for decades, Linux has been supplying secure, reliable OS duties, the word Linux has no familiarity with the general public.
But Linux operating system is everywhere, from enterprise servers to home desktops, home appliances, supercomputers, cars, and smartphones. Everywhere, you will find Linux, and it is on your television, Roku devices, refrigerators, and thermostats. For being one of the stress-free, most secure and reliable operating system available, Linux prides itself as a preferred platform running embedded systems, servers, and desktops all over the world.
What is Linux OS?
In the first place, what do you understand by an OS or operating system? In a physical computer, the management of the hardware is the duty of the computer code known as the operating system. Between the hardware and software, the operating system exists as a layer. Also, in assembler, communicating with a graphics card or addressing a CPU is not what most people want to know. And what acts as a middleman is an operating system like Windows or Linux.
Therefore, Linux, like Mac OS, iOs, and Windows, is an operating system. Essentially, Linux operating system powers Android, which is the most popular platform in the world. The software is likely not to function without the operating system since, as an operating system, Linux manages the communication between the hardware and software.
